HOWTO Convert a starsim geometry to ROOT

Kinematic distributions - Data vs MC
These distributions are based on the following fiducial cuts :
Eta dependence of shower shapes sorted into different preshower bins - Triple Gaussian Fits
Eta dependence of shower shapes sorted into different preshower bins
Background Asymmetry
The following is the double helicity asymmetry for the background extraction of the direct photon analysis. This is the raw extraction asymmetry -- no attempt is made to deconvolve.
Sector dependent shower shapes sorted into different preshower bins - Triple Gaussian Fits
Transverse Shower Profile Distributions
Transverse Shower Profile Distributions Sorted into Different Prseshower Bins - Triple Gaussian Fits (New)
Transverse Shower Profile Distributions
Logarithmic Bin Boundaries
It's taking me longer and longer to remember how to derive this, so I'm posting it as a blog entry.
void logbins()
{
float emin = 0.5;
float emax = 1.0E5;
track significance (St) cut
GOAL : following the procedure of previous post, I should start with single track cut to remove background. (for D0 reco. with SVT/SSD)
