GRB analysis for the science tools checkout

The tools in this area are gtbin, its friend gtbindef, and gtrspgen. The expectation is that the evaluators will be running XSPEC, too, but of course not actually reviewing it.

Unbinned likelihood can also be used for GRB analysis. The Band function is available for likelihood source models.

Short descriptions of the tools and links to available documentation are on the tools summaries page.

Please edit this page to include results, issues, advice, etc., or links to these.

David Band: I worked my way through what will probably be a standard LAT GRB analysis. Thus I extracted the data from the GSSC website, ran gtselect for further selections (e.g., choosing the back of the LAT), ran gtbin to bin the spectra into a PHA file, ran gtrspgen to create a DRM, and then ran XSPEC. Because we need to provide users with 'analysis threads' which walk them through an analysis, I created a thread based on this GRB analysis; see http://glast.gsfc.nasa.gov/ssc/dev/Threads/.

I ran into a number of small problems and bugs, which I reported on JIRA.

Since I am working on defining and simulating the GBM data, I also tried the tools on the simulated GBM I posted. Actually, only gtbin and XSPEC are relevant since I created the DRM (=RSP file) with the simulation package. I was able to analyze successfully a background-less burst, but had trouble with a burst with background (I think this is a result of an incorrect exposure--I haven't tracked this down yet).
