Output text file of total spectrum of sources

[MatthewWhiting]

Request from Mary Putman:

Our sysman has been busy working to get Duchamp working on the new intel Macs so we will hopefully soon have super-duper searching power. :)

We hope to keep using Duchamp, but have a few questions. One problem we are running into is for calculating the total flux of a cloud, Duchamp cuts the spectrum off at the grow level. So that many times, especially for faint objects, the flux is quite a bit off. I'll attach an example page of objects. So what we need to do is fit the total spectrum of the source by hand with a gaussian or two to accurately get the total flux of the object.

Is there a way we can get Duchamp to spit the total flux spectrum into an ascii file? It doesn't seem like it would be too difficult to extract, but we aren't sure where we would adjust things. Using other programs to get the total flux is tricky because of the odd shape for some of the clouds.

There's a couple of possible solutions: write each object's total spectrum to a separate ascii file (ie. two columns, freq & flux); or write one ascii file with a freq column and then a column for each object.

Reply from Mary:

We agree that one file might be better, as otherwise there will be 500 little files clogging up the directory. Tina (cc'd above, graduate student using Duchamp and rapidly becoming an expert :}) said she can write an idl file to deal with either format.

So probably the single file would be better.
