Hi a short update on the MRS spectra. Acceptance maps : Updated mrsgenerate so that it now handles when the platform was pushed back (5729 to 5893). Remaking all the acceptance maps with the following slats missing (don't use database anymore) : slat 1-25, 31, 76, 92, 103-125 (The old files are still there, just moved to *_old, see last email and README files). The plan is now : 1) Get y~0 spectra 0-5 % central from 90 deg 350AB, 1000B 2) Get y~1 spectra 0-5 % central from 35 700B, 40 1000B, 45 700AB I will use Eun-Joos corrections for decays absorption etc. I will hopefully avoid most low pt effects (multiple scattering) and particles from fx beam pipe, by not including low pt (to be defined) points in my fit. I will look again at TPM1 efficiency using the 0-field method described in an earlier mail and use the best estimate from this method (best estimate now is 10% for 0-20% events), I will hope that the TPM2 efficiency is close to 100% and that our matcjhing efficiency for non low momentum poarticles is the same. I will try to estimate a TOFW slat dependent correction 10-25% that is hopefully not very run dependent. If anybody has an idea about any of the efficiency corrections I am very interested.
