Description

All masks in one or more targetting chunks. This file is not normally produced, but can be produced as a convenient summary of all culled and bad fields within a group of targetting chunks.

The target types which are culled are specified in the bit mask culled, where the bits are the same as defined for the primTarget fields in the tsObj file. The bits associated with the badMask field are the same as the badMask field in the tsField file. The field boundaries and scanline and stripe areas are for both amplifiers together; if the badMask field indicates that an amplifier is bad, then those quantities must be adjusted accordingly. The field boundaries are for the scanline region mapped to this field; the primary region mapped to this field is the intersection of the scanline region and the stripe region (except in the south, stripe > 45, where stripe cuts are not applied).
