Examples

The following is a short list of typical task invocations:

• attfilter instexpid=PNU003
  Generate attitude GTI table (with default name) from the unscheduled PN exposure 003 in the current ODF from cone-type filtering expression (with default tolerance angle).
• attfilter instexpid=PNU003 tolangles="0.5*#ARCMIN"
  Same as previous example but set the cone half-opening angle to 0.5 arcmin.
• attfilter instexpid=PNU003 tolangles="0.5*#ARCMIN" gtitable=gti.ds:MYGTI
  Same as previous example but the resulting GTI table gets the name gti.ds:MYGTI.
• attfilter instexpid=PNU003 filtertype=user expression="abs(%RA%-%RA_MED%)<%TOL_1% && abs(%DEC%-%DEC_MED%)<%TOL_2% && abs(%PA%-%PA_MED%)<%TOL_3%"
  Same as first example but the selection expression is given explicitly. It selects periods where the Right Ascension/Declination of the star tracker viewing direction and the position angle independently from each other did not deviate from their median values by more than given tolerance limits (see also description of parameters expression, and tolangles).
