Key:
- To do
p Partially done
^ Done
? Not sure if it's done
- write cross section section in paper
- explain integral in paper
- develop signal generator
p develop high energy and multi-ring fitter
^ write talk for Monday
- write a section on atmospheric backgrounds in paper
^ check index of refraction calculation against tables in the paper
^ write more tests for the solid angle calculation
- use table from paper
^ make sure normal direction is normalized
^ speed up likelihood calculation
- rotate and translate path points in path_init
- create fast interp1d for equally spaced points
- optimize with -O2
- only calculate average time if mu_direct[i] is not too small and PMT is
hit
- add likelihood function which calculates total expected charge and only
loops over hit PMTs
- add fast likelihood which doesn't use a 2D lookup table
- add function to compute the Hessian via finite differences
- add function to calculate covariance matrix
- add function to compute the approximate volume in the likelihood space where
the likelihood is greater than some value
^ add output to likelihood
^ add a set of seed points to start the likelihood
^ minimize the likelihood in a do while loop until it converges to a single
point
^ once the first position is found, compute the Hough transform to look for
other rings
p add rayleigh scattering to likelihood function
- Done, but it's pretty hacky
p add muon shower PDF? delta rays?
- Done for delta rays, but need to add shower photons
- calculate path length through acrylic?
p update estar table with energies above 1 GeV
- added values up to 10 GeV
^ speed up normalize() and interp1d()
^ add shower PDF to get_total_charge_approx()
x compute mean of starting points
^ speed up time PDF calculation for fast likelihood
p calculate psi parameter as a goodness of fit test
- Still need to tweak this. It seems to have a strong nhit dependence
^ add a maximum length for the range
- now only fit to the end of the PSUP
^ add a time limit for the fit
^ multi-particle fit
p optimize CHARGE_FRACTION
? find out why likelihood is sometimes returning nan
^ add pdf for cerenkov light from delta rays
- tweak find peaks algorithm
^ update zebra to allow use of links
- minimum energy for each particle type
^ check all zebra links
^ fix zero logical record size bug in zebra.c
p speed up fit
- have optimized most of the likelihood function. I think further
optimization will require a different technique for evaluating the
integrals
^ nhit cut
p add flasher cut
p default max particles
- submit-grid-jobs fits up to 3 particles by default
^ add environment variable to control where to look for pmt.txt and titles files
- update charge code to handle highest values for qhs and qlx
- use qhs and qlx based on variable in PMT bank
^ fix bug in path_init()
^ load DQXX file based on run number
^ update rayleigh scattering lengths
^ fix delta ray calculation
p figure out why electron energy bias is +10%
- updated code to use a more accurate approximation for the number of
shower photons which seems to bring the bias down to 5%
- update find peaks algorithm to do single particle quick fits
- figure out how to combine SNO fitter data with my fitter for final analysis.
For example, how to apply neutron follower cut?
