How to add and schedule a new target?
There is a MPEC howto. Entering target is very similar, just instead of MPEC one-line you put in target name (resolvable by SIMBAD).
Which images consider rts2-imgproc as good and which as bad?
rts2-imgproc actually have three output scenarios for the images:
bad, when imgproc is unable to read the image. This means that the image FITS header is screwed or that something else failed. Then this image is moved to bad directory in directory from which the image was taken
trash, when image processing routine do not output string with astrometry informations to standard output.
good, when image processing routine (defined in /etc/rts2/rts2.ini file) output string in format
%li %lf %lf (%lf,%lf)
for the scanf. The format is defined in src/plan/connimgprocess.cpp. First is image ID - and integer. Second and third are RA and DEC of image centre expressed in degrees (RA 0..360.0, DEC -90..90). In bracked is error in RA and DEC, again in degrees. Assuming your image centre is at RA DEC 12:00:00 05:00:00 and the telescope was pointed to 12:01:00 05:01:00, the output string should be:
1 180.0 5.0 (.2499999990 .0166666666)
When is selector called to select next target?
Selector (rts2-selector) is process responsible for selecting new observational targets. It sends targets IDs using next command. You can imitate selector behaviour by running rts2-mon, selecting EXEC component and typing: next 1000 to select target with id 1000. The selection is executed on the following occasions:
When observatory is switched to ON state, so the executor knows what to observe
during last exposure on last exposing camera in script, so the executor is keep updated what to observe as the next target
every idle_select seconds, so new targets are selected even if some long script is running. The value of idle_select defaults to 300 seconds (=5 minutes). It can be changed by providing –idle-select parameter to rts2-selector (most probably in etc/rts2/services file).
