Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
attsource	no	string	odf	odf|atthk
Source of the attitude data. If this equals `odf', the environment variable SAS_ODF must be set to point to the appropriate ODF.
odfattsource	no	string	ahf	ahf|om
Whether to use the Attitude History File or the OM pointing history file from the ODF. This parameter is read if attsource=`odf'.
timesource	no	string	user	user|eventlist
If this = `user', the task reads parameters tstart, tstop (or datestrstart and datestrstop) and tstep, and constructs the sequence of attitude sample times from these numbers; if it = `eventlist', the event times from the event list supplied to parameter eventset are used.
usertimestyle	no	string	timestamp	timestamp|datetimestr
This parameter is read if timesource=`user'. If `timestamp' is specified, the start and stop times are read from parameters tstart and tstop as double-precision `timestamps' (seconds since the XMM-Newton reference epoch). If usertimestyle=`datetimestr', the start and stop times are read from parameters datestrstart and datestrstop as strings.
tstart	yes	real	0.0d0
Time stamp of the first time sample. This is read if timesource=`user' and usertimestyle=`timestamp'.
tstop	yes	real	0.0d0
Time stamp of the last allowed time sample. This is read if timesource=`user' and usertimestyle=`timestamp'.
datestrstart	yes	string	0000-00-00T00:00:00
Date-time string of the first time sample. This is read if timesource=`user' and usertimestyle=`datetimestr'.
datestrstop	yes	string	0000-00-00T00:00:00
Date-time string of the last allowed time sample. This is read if timesource=`user' and usertimestyle=`datetimestr'.
tstep	yes	real	1.0	$0>$tstep
Separation between successive time samples. This is read if timesource=`user'.
eventset	yes	dataset
Name of the event-list dataset which supplies time samples from the event times. This is read if timesource=`eventlist'.
pntkwdset	yes	dataset
Name of the dataset from which to read the spacecraft average pointing keywords (usually expected to be the output file of atthkgen). This parameter is read if attsource=`odf' and timesource=`eventlist'.
atthkset	yes	dataset
The dataset (normally this would be expected to be the output files from task atthkgen) which contains samples of the spacecraft attitude. This is read if attsource=`atthk'.
atthkattsource	no	string	ahf	ahf|om
Whether to use the Attitude History File data or the OM pointing history data from the atthkset file. This parameter is read if attsource=`atthk'.
binnedattset	no	dataset	binned_att.ds
The dataset which is to contain the binned attitude data.
maxdelta	no	real	0.02	$0<$maxdelta
A new attitude bin is started if the attitude jumps by more than this amount (in arcsec).
withmedianpnt	no	boolean	yes
Whether to use/calculate median or mean pointing for the *_PNT keywords (and, if attsource=`atthk', whether to access the mean or median atthk data).
