.SH NAME
ASAP \- process single dish spectral data
.SH SYNOPSIS
.B asap
.SH DESCRIPTION
This manual page briefly documents the
.B asap
command. The program has internal help as well.
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
\fBasap\fP is an interactive ipython shell that lets you process
spectroscopic data from astronomical telescopes and make
publication-quality plots.
.PP
The input files can be RPFITS, SDFITS or CASA Measurement Sets,
output can be saved as SDFITS or Measurement Set.
.SH ENVIRONMENT
You may wish to set the following environment variables, to change
the program's behaviour.
.TP
.B ASAPDATA
Path to astronomical ephemeris data files. These are needed to allow
calculations of radial velocity, rest frequency of various transitions, etc.
.PP
They will usually be available in your installation of CASA.
If your casa installation is at /nfs/casa, the ephemeris data should be
in /nfs/casa/data; set ASAPDATA to that path.
.PP
These data files can also be downloaded from
.TP
