Girardi isochrones not working with NGC 188 BV dataset #12

Shane reports:

I think there is something wrong with Girardi isochrones. I tried starting a run on Katmai using the Girardi models and it the code finishes in about 30 seconds. I get this output:

Bayesian analysis of stellar evolution 3882.75 -1538.06 6509 1084.44 -1538.06 4303.68 -5231.19 -126.519 6509 -5231.19 30982.8 6754.71 1084.44 -126.519 6754.71 2878.32 Acceptance ratio: 0.783000 time stamp: Tue May 21 11:11:51 EDT 2013

The funny thing is that the .res and .res.burnin files are both fully written, but it takes literally 39 seconds. You can have a look at the output files if you like. They're under /base9/ngc188/BV and called mcmc.ngc188.BV.fromUBVRIJHK.gir.noBS.aveprobs.res. None of the other sets are doing this as far as I could tell.

Ted checked the output and they have a very low logPost, which means a very unlikely set of parameters. It sounds like the majority of the computation was not being performed, for some reason.

This is now (presumably) as fixed as possible without EEP data. A simCluster bug (issue #50) is currently keeping this from being tested properly.

In the event that there are remaining issues with Girardi, this issue can be re-opened.
