It has just enough time to take WFS image, but not enough time to apply it to PSF. So the result is that active optics is only being applied infrequently. 23:51 pointto BS9152 Tel="ACTIVE" PAM+ PA=330 gs=2 23:54 dice5 off1=6.0 off2=5.0 coord="RADEC" exptime=1.2 Nexpo=40 loopN=10

- Measure AGW4-IRTC2 focus (done May 13 UT, pending data reduction)
- More Transformation Data to test refined transformation (done May 13 UT, pending data reduction)
- Offset tests with refined transformation (some done May 13 UT)
- Check DG rotator scale
- Collect better photometric data on M92 (done 13 May UT)
- EF Data (intra/extrafocal pupils) to confirm Active Optics performance

- Measure WFS and Guider camera saturation levels for AGW4 (done May 13 UT)
- Work on the transistion between AGW3 and AGW4 - it has had problems with oacserver and GCS
- Calibrate timing for IRTC sequences. Issue 2173 (irc wait time versus arrival time on disk)
- Enhance transtar.cl to print a log file with IRAF commands to centroid the cubes.

- Guiding tests versus magnitude
- Guiding scale factor (waiting on analysis of the previous data from last week)
- Investigate the adjustment of exposure times in GCS

- Vibration Data on Bright Stars
- Open-Loop Tracking Data
- Closed-Loop Tracking Data
