Hi This is indeed surpeising; but it could depend on whatever fiducial cuts have been applied. Did you overwrite the old maps ? The old code certainly had a problem in so far it did not include the dead slats in tofw which is crucial for PID, but this effect would in fact not lower the yeilds, so my gueass it has to do with fiducial cuts. On the FS part I have not tried the new banapp. It sounds we really should compare new/old. I still have the old version around and have generated maps, so this may be feasible. I cc the answer to the list because others may have clues to this, and or comments.

The maps I used before were generated half a year ago or something like that....I must admit I was a little surprised. I do not understand how the MRS maps apparently changed so much in this brief time ? Furthermore, using the latest version of banapp, I am unable to generate FS maps due to some bug in the error minimization. The calculation gets stuck at "nan %" ...so far I have been unable to track the bug. Do we have some up-to-date maps for the 62 GeV data somewhere on rcas? Using these would rule out any error I might commit in generating the maps....
