notebook example broken? #86

Closed ngbusca closed 6 years ago

ngbusca commented 6 years ago

I'm trying to run the notebook example SimulationExamples. When running the config step:

desi = specsim.simulator.Simulator('desi', num_fibers=500)

I get an error:

RuntimeError Traceback (most recent call last)

Indeed, the file galsim-fiber-acceptance.fits is missing... is it supposed to be shipped with specsim or should I get it from somewhere else?

sbailey commented 6 years ago

Yes, indeed, update desimodel svn to get data/throughput/galsim-fiber-acceptance.fits, which was added last October at the time of specsim PR #81.

Yep, svn update in $DATAMODEL fixed it! Thanks @sbailey
