Dear All, We have been looking a bit at the TPCs, and have found some odd behaviour. According to the DetectorParameters.txt file, T2 should only have rows 1,2 5,6 9,10 15,16 instrumented. We made (well, Peter made it, but I looked at it!) a plot of the number of sequences in each pad (summed over roughly 15K events, from run 2535, requiring trigger 6) The number of sequences is shown in the eps file by the color (the more red, the more counts) and is displayed in a 2d 'pad map' of T2. One notes that there are a few noisy blocks of 16 pads, as well as some that do not show up. The most concerning is that there seems to be card placed on rows 13 and 14, which disagrees with the info we have (i.e. DetectorParameters.txt) This brings us to the question, which can be answered (presumably) by a visual inspection of T2: which pads and rows are instrumented? If there is no card reading out pads 80-96 on rows 13 and 14, does this imply a problem with the unpacking of the data, or with the original pad map? Or another (set of) problems altogether? Cheers, Peter and Ian. :-) --------------------------------- )-: |Peter H L Christiansen aka PAN @ NBI | |EMAIL : pchristi@nbi.dk | |OFFICE : Tb1 @ NBI | |PHONE : 353 25269 <- New!! | |SNAIL : Sdr.
