Utility Functions

In Miriad there are a few very useful utility functions embedded in a variety of uv tasks that support on-the-fly selection and averaging of channels, spectral windows and polarization correlations.

In both BIMA and ATNF's user's guide, a description of these functions has been given in great details. In this section, an emphasis of these keywords on the SMA data reduction is discussed below. These utility functions appear to be very useful for SMA users to handle spectral data from the powerful SMA correlator. With an instruction, these functions can be utilized for the reduction of SMA data. The contents of the following description of these parameters follow those described in the ATNF's User's guide. Interleaving with some comments on the SMA specifications, the duplication would be convenient for SMA users to use this manual.
