===== How to add and schedule a new target? =====

There is a [[howto:mpec|MPEC howto]]. Entering target is very similar, just instead of MPEC one-line you put in target name (resolvable by SIMBAD):
 <code>rts2-newtarget 5004 M74 01:37:14+15:50:14</code>

===== 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
<code>
%li %lf %lf (%lf,%lf)
</code>
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 brackets are errors in RA and DEC, again in degrees. Assuming your image centre is at RA DEC 12:00:00 05:00:00 and the telescope pointed to 12:01:00 05:01:00, the output string should be:
<code>
1 180.0 5.0 (.2499999990 .0166666666)
</code>

===== 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 behavior 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).
