This appendix contains example analyz sequences used to look at HI spectra.
This routine takes the average of the (gain/za corrected) dumps in each
scan, and analysis is done on the individual correlator sections. Thus
if you have the correlators overapping in frequency, and the galaxy therefore
shows up in more than one correlator this routine will only look at one
`detection' at a time. The commands to by typed are in boldface, followed
by a description of the command. For help with these routines contact Karen
O'Neil (koneil@naic.edu). All this assume you have run once analyz before.
If you have not, please go
to
http://www.naic.edu/~astro/spectral_line/analyz and load hi_now.cmd, mjsr.o, and baseh.o into
you analyz directories. Additionally, if you have not run analyz before, instruction (2)
should read:
