def compute_c2(argv=None):
"""Function to compute the average angular intensity function, <C2(q,dPhi)>, from FXS images
extracted from xtc (smd,idx,xtc format) or h5 files.
Works for Single CPU, Multi-Processor interactive jobs and MPI batch jobs
For a definition of input arguments argv and batch processing instructions see *** mpi_fxs_launch.py ***
compute_c2 produces the following output files:
* Index file : Information about the events processed including time-stamps, beam center, total and peak intensities, streak locations, particle size etc
* I(q) : Average Azimuthal intensities (SAXS)
* C2(q,dPhi) : Average 2-point correlation functions (FXS)
* Bg_img : Average image in polar coordinates
* Bg_norm : Mean subtracted average image in polar coordinates
* Bg_msk : Average mask image in polar coordinates
The I and C2 output data are split in 2 ~equal bins [0 and 1] for statistical comparison to be made
example:
C2_run111_0_29793.dat is the average C2(q,dPhi) from run111 bin 0 where 29,793 images have been processed
C2_run111_1_29718.dat is the average C2(q,dPhi) from run111 bin 1 where 29,718 images have been processed

"""Function to compute the average angular intensity function, <C2(q,dPhi)>, from FXS images
extracted from xtc (smd,idx,xtc format) or h5 files.
Works for Single CPU, Multi-Processor interactive jobs and MPI batch jobs
For a definition of input arguments argv and batch processing instructions see *** mpi_fxs_launch.py ***
compute_c2 produces the following output files:
* Index file : Information about the events processed including time-stamps, beam center, total and peak intensities, streak locations, particle size etc
* I(q) : Average Azimuthal intensities (SAXS)
* C2(q,dPhi) : Average 2-point correlation functions (FXS)
* Bg_img : Average image in polar coordinates
* Bg_norm : Mean subtracted average image in polar coordinates
* Bg_msk : Average mask image in polar coordinates
The I and C2 output data are split in 2 ~equal bins [0 and 1] for statistical comparison to be made
example:
C2_run111_0_29793.dat is the average C2(q,dPhi) from run111 bin 0 where 29,793 images have been processed
C2_run111_1_29718.dat is the average C2(q,dPhi) from run111 bin 1 where 29,718 images have been processed
