Telescope and AGw4 Commissioning at LDG - 03-04 May 2009 MST

Observers:: J. Hill, J. Storm (mtn), A. Rakich (Tucson)
Telescope Operator: David Gonzalez Huerta
Software Support: N. Cushing (mtn) plus M. DelaPena (phone) Telescope Support: J. Rousseau, D. Officer

Summary

This is the first night of Direct Gregorian (Left=SX) observations using AGW4.

After a numerous daytime repairs the telescope has been working decently well. We had some problems with poly times, but never understood what was aggravating them.

Fixed a few minor configuration file problems, including renaming all the files.

Found and fixed a GCS bug where one GCS call checking motor status (in doIsOnTarget) was talking to the wrong AGW PMAC.

Found and couldn't fix an X-flip problem inside GCS (or somewhere). This is critical to continued progress. We must make some kind of patch to GCS tomorrow.

Determined that either the whole AGW or the Guider camera is upside down compared to our expectation. Need to resolve which of them needs to be rotated. JMH: This may be related to accidentally using DETXY offsets when I was intending RADEC offsets, so will have to repeat the position angle orientation tomorrow night.

Have the problem that GCS gets confused between reading out WFS and Guider images. This was fixed at Bent Gregorian, but seems to have reappeared here at Direct (only medium priority).

Had broken clouds all night, and lost about 2 hours to clouds.

Preparations

02 May UT

Have copied pointing model from LBFG. Or more specifically, have added the name of the LFBG pointing model file to the PCSInstrument.conf file.

Have copied the Primary Mirror Collimation Model file from LFBG. It should be a good first guess - modulo the flexure/twist of the M3 swing arm.

Have flipped the signs of Z5 and Z8 zernike terms in /lbt/tcs/current/etc/GCS/AIP_DG_L_RM_sub11.cfg to account for the missing M3 reflection at Direct Gregorian. Have zeroed the Z9, Z10 terms as they will need additional rotation corrections - see Issue 2147. I have not yet made any changes of this nature in IDL.

Question about the entries in the /lbt/tcs/current/etc/GCS/Instrument2AGW.cfg file. They seem to indicate that the AIP_IRTC_DG_L files don't yet exist. All of the above changes were made to the existing AIP_DG_L files. (We straightened this out -sort of- on 04 May (see below).

04 May UT (daytime 03 May MST)

Repair brushed in damaged azimuth motor.

Repair broken air line on SX DG rotator.

18:10 Reboot IRTC Windows PC for good measure. (We aren't using the IRTC tonight as it is at Bent Gregorian.)

18:24 Dave A. is test driving the telescope in azimuth now that motor is repaired.

18:48 stopAGW -u 0 (turn off AGw3)

18:50 switch fiber in control room LIU so agw-control can talk to AGW4 (But how was I able to talk to both AGWs at the same time a few days ago?)

18:52 startAGW -u 1 (turn on AGw4 - which is sometimes called AGW2 ?????)

19:00 Having problems with drive on Left Direct Gregorian Rotator. Cycling power plus Ashby seems to have fixed it.

19:15 DGH points out that M1 (and also M2) collimation tables are not giving a sensible result.

19:22 Copied SXSMIRTFCollimation.dat to SXIRTCIRTCDCollimation.dat so M2 is now in correct position.

19:28 Authorize as IRTC at bent, M1 Collimation looks OK. Reauthorize as IRTC at direct, and now M1 Collimation also looks OK. There must be some funny initialization something going on there. (I haven't checked the PSF or IIF syslogs yet.)

19:30 from IRAF authorize DGTEST, which sends the irc command: irc Authorize 'directGregorian left' IRTC

Details (times in MST)

Open

19:30 Open dome. T=6.5degC, D=-4.6 degC, Wind ~10 m/sec from South. Sky has heavy cirrus, but OK for the checkout stuff we are doing tonight.

21:58 The acquire starts acquiring, so it appears that the timeout is a whopping 15 minutes. (That really hurts the open-shutter percentage.) Adjust IE=-54 CA=7. Seeing fluctuating between 1 and 2 arcsec.

22:04 offset 0 5 (moves star up on Acquire image, but I thought we were in parallactic mode)

22:06 pointto M5_1246 TelM="ACQUIRE" gs=0 PAM+ PA=0 - This time it only took 10 minutes. ??

JMH: All these offsets were DETXY, even though I was intending to do RADEC.

22:17 offset 0 5 - moves star up on acquire image (and didn't move probe) - so I suspect we are rotated by 180 deg.

22:20 offset 0 0

22:21 offset 5 0 moves star left on acquire image.

22:24 Michele is giving us a Patch to PCS v01A with Xflip=TRUE Yflip=FALSE Stop and restart PCS.

22:27 pointto BS9145 TelM="ACQUIRE" gs=0 PAM+ PA=0 - got M2 offload junk IE=-52 CA=+16

22:40 Norm has found a bug in GCS where it appears to be checking motor status for hardwired unit 0. He and Michele are starting to build a patch for GCS.

This is the corresponding oacserver log message:
May  4 05:29:37 agw-control oacserver[24860]: LOG_ERR getdata_1_svc(): Error while flushing PMAC

JMH: All these offsets were DETXY, even though I was intending to do RADEC.

22:47 offset 0 5 moves the star up on the acquire image

22:49 offset 5 0 moves the star right on the acquire image (Xflip really does something - probably not what we want)

22:54 pointto BS9145 TelM="ACQUIRE" gs=8 PAM+ PA=0 - no star found.

23:08 Switch of the other version of PCS (PCS.090503_02b) with both X-flip and Y-flip false. And at the same time, change LEFTZEROPOINT to -180 in PCSInstrument.conf. Stop and restart PCS to get the new version.

23:10 Michele installs the patched GCS. Stop and restart GCSL to get the new version.

23:15 pointto BS9145 TelM="ACQUIRE" gs=8 PAM+ PA=0 - we didn't find the offaxis star, but they fixed the GCS bug that was causing the 10-15 minute delay.

X-flip Problems

23:17 pointto BS9145 TelM="ACQUIRE" gs=0 PAM+ PA=0 - Restore IE=-52 CA=+16

23:19 pointto M5_0531 TelM="ACQUIRE" gs=0 PAM+ PA=0 - hangs waiting for AZ and Rot according to IIF GUI. - Preset timed out. It looks like rotator is getting bad polys.

23:28 pointto M5_0531 TelM="ACQUIRE" gs=0 PAM+ PA=0 - failed without explanation.

23:30 Stop and Restart GCS to get the second patch.

23:31 pointto M5_0531 TelM="ACQUIRE" gs=0 PAM+ PA=0 - failed without explanation.

Change LEFTZEROPOINT from -180 to +180. Stop and restart PCS.

23:34 pointto M5_0531 TelM="ACQUIRE" gs=0 PAM+ PA=0 - Adjust IE=-61 CA=+8

JMH: All these offsets were DETXY, even though I was intending to do RADEC.

23:39 offset 0 5 - moves star down on acquire image

23:40 offset 5 0 - moves star right on image

23:42 pointto M5_0531 TelM="GUIDE" gs=0 PAM+ PA=0

23:44 pointto M5_0531 TelM="GUIDE" gs=0 PAM+ PA=0

23:45 put LEFTZEROPOINT back to 0.0, stop and restart PCS.

23:47 pointto M5_0531 TelM="GUIDE" gs=0 PAM+ PA=0

DGH says rotator faulted when we killed PCS. But there is also a 23:49 complaint about poly t0. Az axis also stopped in there somewhere. See Issue 2162, although there might be other issues too.

23:53 pointto BS9152 TelM="GUIDE" gs=0 PAM+ PA=0

23:57 SFP_Rotation to 0.0, stop and restart GCSL

23:58 pointto BS9152 TelM="GUIDE" gs=0 PAM+ PA=0 - Acquisition offset failed

00:00 LEFTZEROPOINT back to 180.0 - Restart PCS.

00:01 pointto BS9152 TelM="GUIDE" gs=0 PAM+ PA=0 - guided out of the box.

00:09 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=0 - couldn't move probe there (expected in hindsight)

00:10 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=INDEF=229.72 - didn't find the off-axis star.

00:16 SFP rotation back to -180.7, Stop and Restart GCS.

00:17 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=INDEF=229.72 - also didn't find the off-axis star.

00:19 pointto BS9152 TelM="ACQUIRE" gs=0 PAM+ PA=INDEF (some funny delays about Az or rot polys)

00:25 offset 0 5 moves star down on the image, offset 5 0 moves star right.

00:29 pointto BS9152 TelM="ACQUIRE" gs=12 PAM+ PA=INDEF=106.08 - rotator faults again, plus az and el stop tracking. No star found at rotator angle =38. See Issue 2162.

00:33 Manually move rotator to 216 degrees and we find a star (although not centered).

00:36 pointto BS9152 TelM="ACQUIRE" gs=1 PAM+ PA=INDEF=229.72 - didn't find star at 271.

00:37 Manually move rotator to 91 deg, And we saw a star nearby.

Conclusion is that AGW is upside down, OR the guide camera is upside down. Fortunately, we have some configuration parameters that can deal with that. JMH: (Note added later) This conclusion may be confused by the fact that I was accidentally using DETXY offsets when I intended to use RADEC. However, the fact that we acquired off-axis stars says that we had the LEFTZEROPOINT basically correct.

00:42 Set LEFTZEROPOINT to 0.0, Stop and restart PCS.

00:44 pointto BS9152 TelM="ACQUIRE" gs=1 PAM+ PA=INDEF=229.72 - found star at edge of field.

02:00 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=235 - to check if X-flip is correct. - failed acquistion offset was wrong. x=10.3 y=501.8

02:04 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=270 - Probe was well centered on star at x=72 y=527. It looks like acquisition offset is working in CCD-y, but not in CCD-x. That might explain the inconsistency, since our good offsets earlier were mainly in Y.

02:11 Change guideCorrectionFactor to -0.9 (minus)

02:12 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=270 - Acq offset worked in Y, and guiding was working in X but not in Y.

02:22 pointto BS9152 TelM="GUIDE" gs=1 PAM+ PA=270 -

Conclusion: The problem is that GCS has an X-flip built into both the acquisition offset and the guiding corrections. We don't seem to have any configuration parameters that can modify the X-flip. This offset needs to be removed in an instrument configurable way, since we still need it for bent gregorian.

I studied GuidingThread.cpp for a while, and if there is a -1 in there for the x-coordinates, it is extremely well hidden. Could it be a "native flip" associated with CCD readout - that was conveniently cancelled at Bent Gregorian? Could this be a second X-flip inside PCS (one that flips the guide actions and not the SFP coordinates)?

02:26 Change guideCorrectionFactor to +0.9 (normal)
