CMSSW_8_1_0 release

For FTest use this code: https://github.com/cms-analysis/flashggFinalFit/tree/topic-migrate-to-cmssw_747
In this directory replace the file fTest.cpp from the directory: flashggFinalFit/Background/test/ to the the same file from: https://github.com/ivovtin/Envelop/blob/master/FTest/fTest.cpp
To compil the project go to flashggFinalFit/Background
and type

make

1. To run FTest for ggHH analysis use (12 categories):

./runFTest.sh 

To run FTest for VBFHH analysis use (14 categories):

./VBFHHcat_runFTest.sh

2. Check fit plots from FTest. Results of the FTest will be stored at fTestRes_${ext}.dat file.
   
3. While using bbggLimits2018 create a new workspace with orders received from the FTest.
   

CMSSW_10_2_13 release

Use this branch: https://github.com/ivovtin/HiggsAnalysis-CombinedLimit/tree/nckw_option_to_remove_const_offset from CombinedLimit

1. Type:

./Indexes.sh ws_2016-17-18_ttHon0.26_2D_31012020

Then find a combination of functions that gives a minimum of NLL, array of maximum index values, and the array of indices with a combination of functions for Asimov, etc.
2) Then rewrite all the results to submitSCAN.py and ScanStudy.C
3) Run scanning:

./runScan.sh

4. Then run ScanStudy.C to do for minimization
   

root -l -b -q 'ScanStudy.C+("ws_2016-17-18_ttHon0.26_2D_31012020")'

5. Check the output of the program by using

./job.sh

6)Put obtained functions to Envelopejson
