One of my top priorities right now (maybe *the* top priority) is this nitrogen accounting paper.
Ted says to run with the Orion KL accounting - and also to look at Sgr B2, as measured in the HIFI paper by Justin Neill. That's this paper (link).
"HERSCHEL OBSERVATIONS OF EXTRAORDINARY SOURCES: ANALYSIS OF THE FULL HERSCHEL/HIFI MOLECULAR LINE SURVEY OF SAGITTARIUS B2(N)*"
W.W. has a nominal stake on the HCN abundance analysis (assuming non-LTE) in Orion S, NGC6334, and Orion KL. This accounting might fall to me if (in about a month) he relinquishes control over it.
Ted says: gather all of the lines with nitrogen in Caux+11 (IRAS 169... / TIMASS survey) and try to derive column densities. One possible analysis: get the HIFI data and personally fit the HCN lines to do rotation diagram stuff.
The point of this is to supplement the Orion KL accounting with an accounting of molecular abundances for a low-mass star forming region.
We encountered some frustrations with the reduced TIMASS data not being public yet.
Ted said to track down the AFGL 2591 (CHESS) paper(s).
There are three.
1. http://adsabs.harvard.edu.proxy.lib.umich.edu/abs/2013A%26A...553A..11V
"Highly excited linear rotor molecules in the high-mass protostellar envelope"
2. http://adsabs.harvard.edu.proxy.lib.umich.edu/abs/2014A%26A...567A..53K
"Summary of the survey"
3. http://adsabs.harvard.edu.proxy.lib.umich.edu/abs/2015A%26A...574A..71K
"Chemical structure of the protostellar envelope"
Ted also said to find a paper by Kama (2013) on OMC2-FIR4:
http://adsabs.harvard.edu.proxy.lib.umich.edu/abs/2013A%26A...556A..57K
"The Herschel/HIFI spectral survey of OMC-2 FIR 4 (CHESS). An overview of the 480 to 1902 GHz range"
Ted says: "Write a paper with just what we have in hand. Extra stuff is just extra datapoints."
and "Maybe check Herschel archive for IRAS 16293".

Look at the WISH data site - see if I can access it. Ted said he'd follow up on this to investigate things - I'll hold him accountable on that.
Group meetings are Thursdays at 1pm.
