Too many Cosmic Rays #10

Open fergusL opened 4 years ago

fergusL commented 4 years ago

Running the LSST cosmic ray algorithm is producing too many detections as noted in PR #9

@danjampro has just set a high detection cap of 1000000 for now.

There are a few parameters that control the number of CRs (implemented here):

Raising this contrast parameter reduces the number of CRs:

config.repair.cosmicray.cond3_fac

Lowering this contrast parameter reduces the number of CRs:

config.repair.cosmicray.cond3_fac2

This sets the minimum brightness for a CR detection:

config.repair.cosmicray.min_DN

With the current test data and default values, this will give an excessive amount of CR detections. We need to determine the right settings for Huntsman.
