These files contain updated MinI calibrations. They will account for the
front-calibration already in place. To use them, one must load them into the
private database. Unfortunately, at this point (as far as I know), one must
completely reimport the database, i.e. an update via gmake database.load will not work.
26 May:
Calibration using Leif, J&F, QC measurements, in order of priority,
with QC measurements scaled according the Leif's parameterization, forward
and backward crystals parametrized separately. This plot shows what type of calibration is used for each crystal (black=QC, red = J&F, blue= Leif).
EmcMinIDigiCalib.3.0.dat: This file will apply the MinI constants relative to the Jordan's front end scaling.
EmcMinIUncalibrate.1.0.dat: This file will only "undo" the front-end calibration, for those who wish to look at raw preamp output.
27 May:
These files are for runs before 2361, before Jordan applied the front end calibration. Runs after 2361
should use the files above.
EmcMinINoFrontEnd.1.0.dat
12 August:
Ir2 boot now runs with all constants set to one, and the front end has been
updated with calibrations from bhabhas, mips and QC. These calibrations are in
the file
frontend.dat
