attcalc (attcalc-4.39) [xmmsas_20230412_1735-21.0.0]

Examples

• attcalc eventset=events.dat (uses ahf attitude within the current ODF [set via the environment variable $SAS_ODF] to calculate event X/Y coordinates, referenced to PNT values in atthk.dat)

• eventset=events.dat attitudelabel=fixed refpointlabel=obj fixedra=23.645 fixeddec=-10.034 fixedposangle=23.4 (uses fixed attitude to calculate event X/Y coordinates, referenced to the OBJ RA/Dec values in the event file).

• attcalc eventset=events.dat attitudelabel=ahf refpointlabel=user nominalra=100.0 nominaldec=10.0 imagesize=1.0 (uses ahf attitude in the current ODF to calculate event X/Y coordinates, referenced to user defined RA/Dec. Size of effective image increased).
