Take Sequence of ImagesTITLE Take a Sequence of Images (LP 20) PURPOSE To take a sequence of images from C1-EIT DESCRIPTION This Observation Program is used to take normal images, using shutters, from C1,C2,C3 and EIT. This program calls op_take_normal or op_build_fp_line_scan multiple times and provides a "macro" capability to the scheduling. The operator schedules this LP with the parameters which include which of the 3 telescopes are to be used, as well as which parameter table, FW position, PW position, and the image processing table number to process the image data. If a telescope is declared down (non-operational) this code would simply by-pass that particular telescope, and work at the others. This program requires many rows of the image_control array for determining the image processing for the first and successive images. LP Number 20 INPUT PARAMETERS Parameter Description # 0 Campaign ID 1 Bit 0-3 Program ID Bit 4-7 Num of Steps (for Build Line Scan Only) Bit 8-9 End Condition - Cyclic, Iterations Bit 10-15 Num of images 2 Bit 0,1 Camera ID Bit 2,3 Camera Parameter Table 1 = primary 2 = alternate 3 = calibration Bit 4,5,6 Filter Wheel (0-4) Bit 7,8,9 Polarizer Wheel (0-4) Bit 10-14 Image Processing Table . . . Continue same layout for each image (up to 9). A zero for num_images is an error. EXAMPLE: Parameter Description 0 101 = Campaign ID 1 8713 = 0x2209 : Program ID = 09 : End Condition = 2 (Iteration) : Num of Images = 16 2 276 = 0x0114 : Camera = 0 (C1) : Camera Parameter Table = 1 (primary) : Filter Wheel = 1 : Polarizer Wheel = 2 : Image Proc Table = 0 MODULE NAME OP_TAKE_SEQ.C |
