Commands#

resumeGuiding#

Description: Resume current guider operation. This command will restart a guider operation with the last values used in startGuiding. If no previous startGuiding command was issued, since the last time the CSC was enabled, the command will be rejected.

EFDB_Topic:: Guider_command_resumeGuiding

startGuiding#

Description: Start guiding using the input information. The command returns as soon as guiding starts, before the first interation is completed. If it fails to find a guide star in the provided guider region, the CSC will go to fault state.

Description: Vector with 8 elements specifying the origin of the guider ROI window in the x-axis for each guider sensor.

roiXRight#

IDL_Type:: long
Units:: pixel
Count:: 8

Description: Vector with 8 elements specifying the end of the guider ROI window in the x-axis for each guider sensor. If roiXLeft=roiXRight=0, for a particular element of both arrays, it assumes no guider region for the equivalent guider sensor. For each valid entry in roiXRight/roiXLeft the width must respect the ROI constrains (see requirement CA-TS-GDR-ICD-0006 in LSE-66).

roiYTop#

IDL_Type:: long
Units:: pixel
Count:: 8

Description: Vector with 8 elements specifying the end of the guider ROI window in the y-axis for each guider sensor. If roiXBottom=roiXTop=0, for a particular element of both arrays, it assumes no guider region for the equivalent guider sensor. For each valid entry in roiXBottom/roiXTop the width must respect the ROI constrains (see requirement CA-TS-GDR-ICD-0006 in LSE-66).

expTime#
