DESCRIPTION

ZEEETA is a MIRIAD task to compute the Zeeman S/N parameter eta = (dI/dnu)_rms / sigma  

PARAMETERS

in
The input Stokes I image in vxy order. No default.
out
The output eta image, if blc,trc is not specified
sigma
r.m.s. noise of signal free I spectrum
chan
The channel range. Default is all channels.
blc
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 the terminal.
trc
Specify the trc of the spatial window in pixels
der
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
