Parameters

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

Parameter	Mand	Type	Default	Constraints
eventset	yes	dataset
Name of the event-list dataset.
xcol	no	string	X
Name of the column of the event list to which to write the X coordinate values.
ycol	no	string	Y
Name of the column of the event list to which to write the Y coordinate values.
imagesize	no	real	0.36
Half-size of final image (in degrees).
attsource	no	string	binned	binned|odf|fixed
Source of the attitude data. If this equals `odf', the environment variable SAS_ODF must be set to point to the appropriate ODF.
inbinnedattset	yes	dataset
Name of the dataset from which to read the pre-binned attitude data (usually expected to be the output file of attbin). This parameter is read if attsource=`binned'.
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'.
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'.
maxdelta	no	real	0.02	$0<$maxdelta
A new attitude bin is started if the attitude jumps by more than this amount (in arcsec). This parameter is read if attsource=`odf'.
withmedianpnt	no	boolean	yes
Whether to use/calculate median or mean pointing for the *_PNT keywords. This parameter is read if attsource=`odf'.
writebinnedatt	no	boolean	no
Whether to write the binned attitude to file. If `yes', the data is written to outbinnedattset. This parameter is read if attsource=`odf'.
outbinnedattset	yes	dataset
The dataset which is to contain the binned attitude data. This parameter is read if writebinnedatt=`yes'.
attra	yes	angle		$0\le$attra$\le360$
Right Ascension of the spacecraft attitude. This parameter is read if attsource=`fixed'.
attdec	yes	angle		$-90\le$attdec$\le90$
Declination of the spacecraft attitude. This parameter is read if attsource=`fixed'.
attapos	yes	angle		$0\le$attapos$\le360$
Position angle of the spacecraft attitude. This parameter is read if attsource=`fixed'.
tangdirstyle	no	string	pnt	nom|obj|pnt|user
Source of celestial coordinates of the point at which the projection plane is tangent to the celestial sphere. Values `nom', `obj' or `pnt' cause the task to read these coordinates from keywords in the event list which have the form *_NOM, *_OBJ and *_PNT respectively, where * is either RA or DEC. (Note that the PNT values have already been written to the file by evproject.) If tangdirstyle=`user', the coordinates are read from parameters tangdirra and tangdirdec.
tangdirra	yes	real		$0\le$tangdirra$\le360$
RA of the point at which the projection plane is tangent to the celestial sphere. This parameter is read if tangdirstyle=`user'.
tangdirdec	yes	real		$-90\le$tangdirdec$\le90$
Declination of the point at which the projection plane is tangent to the celestial sphere. This parameter is read if tangdirstyle=`user'.
