How to get a NOEMA spectrum to load in CLASS

This is a post to demonstrate how I got a spectrum from NOEMA (formerly PdBI) interferometry to load into CLASS.

I have my data located in the following directory:

directory:
/Users/tsrice/Documents/Data/NOEMA/W15AI/maps

file:
l1455irs1_WIDEX.lmv-clean

then I did this in CLASS, from the "maps" directory:
$ class
LAS >
file out mycube.bin single
lmv l1455irs1_WIDEX.lmv-clean
file in mycube.bin

! this makes a box 2'' x 2'' to extract spectra from:
set match 2
find /offset 0 0

set weight equal
average /nocheck position

plot

I learned this from the following page (102):

I have bothered with all of these steps in order to get WEEDS to work on a NOEMA spectrum.
