Take Dark Current ImageTITLE Take Dark Current Images PURPOSE To take dark images from C1-EIT DESCRIPTION This Observation Program is used to take dark images, from C1, C2, C3 and EIT. The filter, polarizer and shutter mechanisms are not moved. The operator schedules this LP with the parameters which include which of the 4 telescopes are to be used, as well as the exposure time, and the image processing table number to process the image data. The calibration table will be used to obtain the camera parameters. If a telescope is declared down (non-operational) this code will exit. LP Number 5 INPUT PARAMETERS Parameter Description # 1 Telescope (0-3) 2 Parameter table 1 = primary 2 = alternate 3 = calibration 3 Exposure Time ( in 1/32s ) 4 Imaging Processing Table Number MODULE NAME OP_TAKE_DARK.C |
