ipvcalc \- calculate MDI velocity from pairs of difference grams..SH SYNOPSIS
.B ipvcalc
\fI[-qv] [argument= value ...]\f
.SH DESCRIPTION
\fIipvcalc\fR produces Dopplergrams using the onboard "MDI" algorithm fordetermining velocity
from pairs of difference grams containing Sa (I1 - I3) and Sc (I2 - I4),where I1 through I4 are intensities measured at nominal filter positions of-120 mA, -40 mA, +40 mA, +120 mA from the Lyot filter transmission 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.
