Can you email us Kartik’s powder-pattern plot so Mikhail can try to match it?

The files are in /reg/neh/home4/mliang/analysis/rel-cxif5315/work1/kartik
Here is the code I got from David to open things:
C++
string imageFile = "XXXX.bin";
double *imageData;
FILE *fp;
int area = 1701*1701;
imageData = (double*)malloc(area * sizeof(double));
fp = fopen(imageFile.c_str(), "rb");
int ret = fread(imageData, sizeof(double), area, fp);
fprintf(stderr, "fread %s returned %d entries\n", imageFile.c_str(), ret);
MATLAB
imfileID = fopen(XXXX.bin');
im = fread(imfileID,[1701 1701],'double’);
Images from files of kartik
Kartik's images from binary files were produced by the sctript
cxif5315/plot-image-from-binary-file.py
background, weights, data
background subtracted data
Images generated by cxif5315 scripts
Averaged over selected events Fraser transformed images are generated by the script

Image after loose cuts on fit
FIT_PROB_MIN = 0.1 # relative 1
FIT_PHI_ERR_MAX = 2 # deg
FIT_BETA_ERR_MAX = 10 # deg
FIT_DPHI_MAX = 10 # deg
FIT_DBETA_MAX = 20 # deg
Image after tight cuts on fit
FIT_PROB_MIN = 0.1 # relative 1
FIT_PHI_ERR_MAX = 1 # deg
FIT_BETA_ERR_MAX = 5 # deg
FIT_DPHI_MAX = 5 # deg
FIT_DBETA_MAX = 10 # deg
- color range is shrink in order to illuminate arc region
