Partial Coding Map for the Swift BAT Instrument
The BAT team is making available several helpful files and images
to aid potential Swift users in understanding the BAT capabilities.
See the COMMENTs lines in the FITS files for more details.
The FITS files contain these positions expressed in BAT tangent
plane coordinates (IMX = BAT_X / BAT_Z and IMY = BAT_Y / BAT_Z),
sky unit vector, and RA / DEC. For conversion to sky
coordinates, a spacecraft attitude of RA = 0, DEC = 0, ROLL = 0
was used. The RA and DEC are centered on zero, so there are
negative right ascensions.
