Computer Science

Scientific paper

This program is a version of the standard focus sweep used since cycle 7. It has been modified to go deeper and uses more narrow filters for improved focus determination. For Cycle14 a new source has been added in order to accomodate 2-gyro mode: the open cluster NGC1850. The old target, the open cluster NGC3603, will be used whenever available and the new target used to fill the periods when NGC3603 is not visible. Steps: a Use refined target field positions as determined from cycle 7 calibrations b Use MULTIACCUM sequences of sufficient dynamic range to account for defocus c Do a 17-point focus sweep, +/- 8mm about the PAM mechanical zeropoint for each cameras 1 and 2, in 1.0mm steps. d Use PAM X/Y tilt and OTA offset slew compensations refined from previous focus monitoring/optical alignment activities
