D.15. BATMASKWTIMG 167
(aperture = “CALDB”)[filename ]
BAT aperture map file name, which contains the coded mask pattern and alignment parameters.
If the CALDB database is set up, then CALDB can also be specified. If several
aperture types are available in the CALDB, the user can specify CALDB:apertype. Valid
values of apertype are currently: FLUX, DETECTION, or MASK EDGES; for apertures
optimized for flux reproducibility, detection sensitivity, or for the shadow of the edge of the
mask, respectively.
(coord type = “sky”) [string ]
Method of specifying the source coordinates. It should be one of: “sky”; “tanxy” (coordinates
expressed in tangent-plane coordinates); “cartesian” (source at cartesian position in BAT
coordinates); “unit” (unit vector direction in BAT coordinates); “fswlonlat” (flight software
phi and theta); “grmclonlat” (source at simulator longitude and latitude). All coordinate
types but the first are specified in the instrument coordinate system.
(time = 0) [real ]
Time associated with the mask weighted image. When coordinates are used, it is also possible
for the attitude to change as a function of time. Specify the mission elapsed time of interest
with this parameter. A value of 0 (the default) indicates to use the first row of the attitude
file, or the time in ‘infile’ if it is present. Ignored for non-sky coordinate systems.
(rebalance = YES) [boolean ]
If YES, then the mask weight map will be adjusted so that its additive mean is zero. If NO,
then, the map will be written unadjusted.
(bat z = 0) [real ]
Position of the source in BAT Z coordinates, if coord type is “cartesian” (in units of cm).
(incatalog = “NONE”) [string ]
Input source catalog containing source positions. The catalog should contain one row per
source. A value of NONE indicates that the source coordinates should be taken from the
command line.
(racol = “RA OBJ”) [string ]
Column name of the first coordinate value in the input catalog, typically right ascension.
(deccol = “DEC OBJ”) [string ]
Column name of the second coordinate value in the input catalog, typically declination.
(namecol = “NAME”) [string ]
Column name of the source name in the input catalog. This value is written to the output
keyword named ‘OBJECT’. If NONE is specified, then this column is ignored.
(catnumcol = “CATNUM”) [string ]
Column name of the source catalog number in the input catalog. This value is written to the
output keyword named ‘CATNUM’. If NONE is specified, then this column is ignored.
(outtype = “WEIGHTS”) [string ]
Type of output map (one of WEIGHTS, ZERO or NONZERO). For ZERO, the test (weight
== 0) is performed on each pixel; for NONZERO, the test (weight != 0) is performed.
(1=true; 0=false).
