General comment: Currently the process is quite cumbersome, but flexible. There are
several places where editing is required. This could be streamlined with a common input
file. The code is "legacy" copied from previous work and adapted for "quick studies."
However, just in producing two different configurations, I find that it takes time to
generate the geometry files and configure the program in a consistent manner.
Files that need editing as geometry changes
input.dat - currently the only parameter modified is 'kine' last argument (z vertex)
gukine2 - generation of light ray distributions
draw_trigs.kumac - kumac which draws light guides inside of GEANT3 (gbcal-int executable)
uhinit.f - defines histograms, data lines must be modified as geometry changes
ugeom.f - defines geometry, must be updated as geometry changes in several places.
In particular, see GEANT3 User's Guide GEOM 001 and GEOM 050
gustep.f - called at each step, fills histograms, data lines must be modified as geometry changes
plot_guide.kumac - kumac which plots histograms output by gbcal-int in file gntbcal.hbook
Files that might need editing occasionally:
cerenkov.f - Must be changed if material parameters are changed (e.g. attenuation length,
reflectivity, index of refraction, etc.). Note that the detailed wavelength
dependence of many parameters is by-passed. A simplified routine would currently
suffice.
