After fixing the transform function, I merged the code with Theresa's RA-Dec code and redid the reconstruction of the chicos data set.
There was an error creating shower images, so I redid the reconstructions.
shower fileShower file with only high-energy showers (LogE>19.6): high-E shower file
There are 65 showers, 37 of which pass a cut on angle, with theta < 1 radian (57.3 deg).
Shower file with only best angle estimate showers and high-energy: best shower file
I chose 25 showers, 14 of which have theta < 1 radian. Only the 14 which pass are in the file.
