172 APPENDIX D. BAT SOFTWARE TOOL REFERENCE
ra [real ]
The right ascension of the target in degrees.
dec [real ]
The declination of the target in degrees.
(atmdepth = 5.0) [real ]
Thickness of the earth “atmosphere” in kilometers. Points within this thickness are assumed
to have zero exposure.
(rearth = 6378.1) [real ]
The effective radius of the earth in kilometers. The default value is the mean equatorial
radius (a conservative number).
(rmoon = 16.0) [real ]
The effective radius of the moon in arcminutes. The default value is conservatively set at 0.5
arcminutes larger than the true value.
(rsun = 16.5) [real ]
The effective radius of the sun in arcminutes. The default value is conservatively set at 0.5
arcminutes larger than the true value.
(constraints = “EARTH,MOON,SUN”) [string ]
A comma-separated list of the constraints to check (any of EARTH, MOON, SUN and FOV).
“FOV” refers to a BAT field of view check (i.e. whether the source has a partial coding
fraction of at least ‘pcodethresh’ percent).
(imxmin = “INDEF”) [string ]
Minimum value for the image (tangent plane) IMX coordinate for the target. INDEF indicates
no selection.
(imxmax = “INDEF”) [string ]
Maximum value for the image (tangent plane) IMX coordinate for the target. INDEF indicates
no selection.
(imymin = “INDEF”) [string ]
Minimum value for the image (tangent plane) IMY coordinate for the target. INDEF indicates
no selection.
(imymax = “INDEF”) [string ]
Maximum value for the image (tangent plane) IMY coordinate for the target. INDEF indicates
no selection.
(thetamin = “INDEF”) [string ]
Minimum value for the image THETA angle (angle of the target from the boresite). INDEF
indicates no selection.
(thetamax = “INDEF”) [string ]
Maximum value for the image THETA angle (angle of the target from the boresite). INDEF
indicates no selection.
