Take calibration lamp imageTITLE Take Calibration Lamp Images PURPOSE To take calibration lamp images from C1-EIT DESCRIPTION This observation program is used to take calibration lamp images, possibly using shutters, from C1, C2, C3 and EIT. C1 and C2 have lamps that illuminate the front door, so the door must be closed when these are scheduled to be run. C2 and C3 have lamps that illuminate the back of the shutter and therefore don't require the door to be closed, and of course the shutter won't move. The EIT has a lamp that illuminates the CCD directly. The operator schedules this LP with the parameters which include which of the 4 telescopes are to be used, as well as which FW position, PW position, and image processing table number to process the image data. The calibration parameter table will be used. LP Number 17 INPUT PARAMETERS Parameter Description # 1 Telescope (0-3) 2 Parameter table number 1 = primary 2 = alternate 3 = calibration 3 Filter wheel position (0-4) 4 Polarizer wheel position (0-4) 5 Image processing table 6 Lamp Number 2 = Door 3 = Shutter MODULE NAME OP_TAKE_CAL_LAMP.C |
