Slitmask Design Software

Current Status

• At present, two slitmask design programs are in use for designing LRIS slitmasks:
  ... 1. autoslit (written by Judy Cohen) is the officially supported software (written in FORTRAN).
  ... 2. simulator (written by Drew Phillips) is an IRAF task, originally based on autoslit but now evolved to be completely independent.
• Both programs currently handle differential refraction.
• simulator includes dispersion vector to help observer plan mask PAs.

These programs will/may need to be modified to include distortions produced by the ADC.

• The level of these distortions is TBD.
• If distortions are non-negligible, the programs will need to provide indications of the acceptable range in Hour Angle for a given mask design.
• Opportunity to consolidate LRIS/DEIMOS/ESI slitmask design code.
