vcalc \- strategy module for vcalc: calculation of velocity (uncalibrated lineshift) from sets of four MDI filtergrams using the MDI method.SH SYNOPSIS
.B vcalc
\fI[-qv] [argument= value ...]\f
.SH DESCRIPTION
\fIvcalc\fR produces Dopplergrams using the onboard "MDI" algorithm fordetermining velocity from sets of filtergrams exposed at the nominalfilter positions of -120 mA, -40 mA, +40 mA, +120 mA from the Lyot filtertransmission center, respectively.
The \fB\-q\fR option prints out the list of required arguments and their
default or environmental values, then quits. The \fB\-v\fR option sets \fIverbose\fR mode, redirecting history from \fIstdout\fR to \fIstderr\fR.

.SH DIAGNOSTICS
.SH BUGS
Doesn't die gracefully or do anything useful on failure to find data.
\fIipvcalc\fR and \fIvcalc\fR are very similar and might be consolidated. .SH AUTHOR
