zeeeta - Compute Zeeman parameter eta
ZEEETA is a MIRIAD task to compute the Zeeman S/N parameter
eta = (dI/dnu)_rms / sigma
The input Stokes I image in vxy order. No default.
The output eta image, if blc,trc is not specified
r.m.s. noise of signal free I spectrum
The channel range. Default is all channels.
Specify the blc of the spatial window in pixels. If unset,
the whole image is done, with no spatial summing, and
an output eta image made. If blc and trc are set, then
eta is computed for this window, and the results output to
Specify the trc of the spatial window in pixels
1 or 2 for one or two sided derivative. If you would
like to see a plot of the last derivative spectrum, include
a `p' as well. E.g., 2p or 1p
