README FILE FOR rcompact


DESCRIPTION: 

Export program to read compact summary files of populations from Martin,
Schwarz, and Mandy 1996, ApJ, 461, 265.

(for A values and energies see readme_export in the ftp subdirectory
above this)

(for collision rates see Martin and Mandy 1995, ApJ, 455, L89 or the ftp
subdirectory ../../h2hdist).


rcompact reads in the populations and includes an interactive
test/request.  
[e.g., for 2000 K and n = 1.d4 cm-3, the population of the (4,5) state
(column index 212) is 5.407951280003359D-07]


Individual subroutines can be broken out and adapted for other uses.


FOR EXAMPLE -- EMISSION LINE EMISSIVITIES:


To generate emission line emissivities (ergs cm-3 per H2), use these
populations and the above-mentioned A values and energies.  Use vjcol to
find the column index of the initial (j) and final (i) states.  Then the
emissivity is pop(j)*a(i,j)*(ecol(j)-ecol(i))*1.9864476e-16.


REQUIRED FILE AND DATASETS: 

rcompact.f, msm*


TO RETRIEVE VIA ANONYMOUS FTP:

ftp -i ftp.cita.utoronto.ca
anonymous

Have fun.
