Bug Fix: Addressing #37

[bdorney]

Description

Addressing https://github.com/cms-gem-daq-project/gem-plotting-tools/issues/37

Now the overlay_fit() function in anaUltraScurve.py will take the event count as an input and use it for the fit.

Types of changes

• [X] Bug fix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to change)

Motivation and Context

If someone used the -b option the fit defined in overlay_fit() would not be correct for scurves taken with event counts different from the default.

How Has This Been Tested?

I re-ran an old anaysis:

anaUltraScurve.py -i$DATA_PATH/GE11-VI-L-CERN-0001/scurve/current/SCurveData.root --ztrim=4 -b -f
