Multi-slit masks can be used with the R.C. Spectrograph (RCSP) at the Mayall 4-Meter Telescope. Covering a field of five-arcminutes, the entrance mask consists of an array of slitlets that can be centered on 10-20 objects in the field. Local sky measures are obtained by extending the slitlets, when space permits, beyond the object. Using typical 2.5-arcsecond wide slitlets, resolutions in the range 1.5-15Å are available with the RC Spectrograph in off-axis collimator mode. Using the lower resolution Cryogenic Camera, resolutions in the range 8-30Å are available.
Improved metal masks, offering better spectrograph throughput, went into use
in January 1996.
A PostScript version of this manual is available.
