Converting GILDAS-CLASS data cubes (lmv files) to fits

As usual, CLASS documentation is nearly impossible to navigate. At the end of the CLASS "introduction" (gildas-intro.pdf) there is a subtle and obscure reference to the vector\fits command. The conversion is actually relatively straightforward:

vector\fits outfile.fits from infile.lmv

Gildas CLASS

It's absurdly difficult to find help on GILDAS Class, probably because you can't google "class" and most people probably don't label every piece of code with "GILDAS class".

Anyway, here are some scripts that I refer back to often:

file in August2009BGPS.dat
file out August2009fits.dat multiple
on error "file out August2009fits.dat"
say "READ IN FILES"
define character sourcelist*10[300]
accept sourcelist /column observed_sources.txt
on error "continue"
get 1001
set window -100 160
set mask -400 -100 160 400
set mode x -400 400
set align velocity
for i 1 to 161
say "Working on SOURCE "'i'
find /source 'sourcelist[i]' /telescope "CSO 4GHZ IF1" /offset 0 0 /quality 5
average
on error "@avplot2 'sourcelist[i]' 'i'; next"
base 3
line 0
min
plot
vis
write i
! on error "continue"
next


and


file in araya-2004.cls
find
define character filename*20
for i 1 to 20
say "Working on source "'i'
get next
let filename "araya-2004_"'i'".fits"
say "fits write "'filename'" /mode spectrum"
fits write 'filename' /mode spectrum
next

!file in araya-2002.cls
!find
!define character filename*20
!for i 1 to 42
! say "Working on source "'i'
! get i
! let filename "araya-2002_"'i'".fits"
! say "fits write "'filename'" /mode spectrum"
! fits write 'filename' /mode spectrum
!next
