Summary

Note: MODS Red channel files are being named incorrectly, the sequence number is only three digits. It persisted on restart.

3:00 MST Opened!

Details

03:30 acqMODS wolf1346.acq
  • modsAlign -r mods1r.20130911.002.fits
  • offset: -3.319 +5.674 -> 003
  • -13.00 X to get good image of slit -> 004
  • +12.32 X to re-center -> 005
  • PCSInstrument MODS1 leftpointingorigin updated to -2.4 3.4
  • PCS restarted

03:50 acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.006.fits
  • Star offset ~ +6", wrong sign?
  • Change sign to +2.4 +3.4, restart PCS

acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.007.fits ...same place?
  • Change sign to +2.4 -3.4, restart PCS

04:05 acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.008.fits
  • offset: -5.4 +7.9

04:08 acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.009.fits
  • offset -5.3 +7.6
  • slit center now looks to be at ~517, star at ~505! Frame 010

Verify PCSInstrument.conf back to 0.0 0.0 on pointing origin for MODS1
restart PCS

04:17 acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.011.fits
  • star at 550 527, offset -5.4 +7.7
  • same as previous acq.

acqMODS is moving the star to coords 505,590 from a starting position of 550,525. In frame 002 the wide slit did appear to be centered at about 505 in X but in subsequent frames it is centered more around 517.

04:31 BS9183 sent from iraf with hotspot offset of +3.2 -4.6 (assumed mm)
  • Take image manually
  • modsAlign -r mods1r.20130911.013.fits
  • offset -9.7 +15.5

04:31 BS9183 sent from iraf with hotspot offset of -3.2 +4.6 (assumed mm)
  • Take image manually
  • modsAlign -r mods1r.20130911.014.fits
  • offset 0.49 -0.12
  • 015 post offset (forgot to insert slitmask)
  • 016 w/slitmask 2.0s
  • star @~505 but slit still appears @ ~518

04:31 BS9183 gs#2 for different PA, sent from iraf with hotspot offset of -3.2 +4.6 (assumed mm)
  • Take image manually
  • modsAlign -r mods1r.20130911.017.fits
  • star @ 556 419

04:56 BS9183 gs=0
  • With PO offsets it fails to do the preset (guide probe can't be moved there)
  • 018 before manually locked IMCS
  • w/o hotspot offsets 019 @ PA=180, 020 @ PA=0
  • 021 w/slitmask after manually locking IMCS again

05:18 acqMODS wolf1346.acq again...
  • modsAlign -r mods1r.20130911.022.fits

  • post offset 023
  • after aother IMCS lock 024

Slit in correct position...IMCS was not locking because exposure times were too short?

05:25 Closing, high and rising humidity, dew on all-sky camera.

05:45 Preset to BS9183 ACTIVE gs=0 no hotspot offset on cmd line or in PCSInstrument.conf

PCSInstrument.conf changed to +3.0 -5.0
PCS restarted

05:47 Preset to BS9183 ACTICE gs=0 again, no hotspot offset on cmd line but with PCSInstrument.conf modified

Stage sent to 0 0 in both cases, so PCS is not reading the file in /lbt/tcs/current...

Testing /home/telescope/TCS/Configuration/PCS/PCSInstrument.conf
  • MODS LEFTPOINTINGORIGIN set to 3.0 -5.0
  • After preset, MODS sent stages to -2.9 -4.9
  • PCSInstrument.conf reset to 0.0 0.0 on the PO
