h1. MAROC Scaler Data Analysis test h2. How to run the scripts # *Scripts are currently located under the following directories in solid@tunl11* # Scripts is located at "/home/clasrun/rich/suite1.0/sw/ana/ped" # library is located at "/home/clasrun/rich/suite1.0/sw/ana/lib" # The output files are at "/home/clasrun/rich/suite1.0/results/scalers" # The main library is created by compiling the code "rich.C" # The script "recoPed.sh" take the input file and a integer number (0 or 1) >> 0 is for pedestal run >> 1 is for dark current run h2. Example to run the code ./recoped.sh filename 0 h2. It runs the following scripts" # "*richDoHistoCount.C*">> It runs the function doHistoCount () in rich.C *Output:* 1) stat.txt >> It gives the mean, rms of the pedestal in entire range 2) dead.txt >> Channel having the count less than 1 3) noisy.txt >> Noisty channels. Channel with RMS>=4 4) hot.txt >> channel with rate greater than 10 kHz 5) rate.txt >>Dark current rate for individual channel between 300-500 6) chip.txt >> mean and rms of pedestal for each pmt (average of all pixel within same pmt) 7) chiprate.txt >> mean and rms of dark current (average of all pixel within same pmt) 8) histo.root >> hCount[channel]-> Rate at different threshold >> hRate[channel]-> Dark current rate in region between 300-500 >> hShoulder[channel]-> Dark current rate from Threshold to threshold +25 unts # "*richPlot.C*" >> runs the function plot ( 1 , datatype) from rich.C >> datatype = 0 (pedestal) or 1 (dark current) *Output:* 1) range.txt >> mean, rms of the pedestal fitting the histogram with guassian in narrow range. It also gives the maximum value of Threshold (DAC unit) which has rate >1. That is the end of tail of histogram hCount. For dark current range is take between (150,650) while for pedestal its in between 170,220) 2) "largePedestals.txt" >> if the mean pedestal + 10*sigma > Threshold pedestal. Then that channel is flagged as large pedestal and written in file. 3) "slope.txt" >> slope at 5 different point above pedestal. Basically its measure of flucatation of of dark current above threshold. >> how is slope determinded 5 point (Threshold +25 , Threshold +50,Threshold +100 , Threshold +200,Threshold +400) are picked Then Dark current rate at each point is computed (average of 7 points in step of 3.5 DAC units) 4) plot.pdf >> Its the fit to the pedestal with guassian in narrow range around the peak ##################### KEY NOTE ########################### Key note "range.txt" is the output with guassian fit but "stat.txt" contains same information without fitting but taking values from direclty histogram (for example h->GetMean() in case of "stat.txt"). So "stat.txt" is only good when pedestal is very high. # "*richDisplayCount.C*" >> display2(filename, opt, ymin,ymax) from "rich.C" filename is the name of file used to draw information opt: is 0 (pedestal) or 1 (dark current) ymax, ymin >> range to draw plot *Output:* 1) display1.pdf >> plot1 >> xpixel:ypixel:pedestal_mean (using "stat.txt") >> plot2 >> 1D histogram of pedestal mean value >> plot3 >> mean pedestal for different channel within same PMT (for all PMT) 2) display2.pdf >> plot1 >> xpixel:ypixel:pedestal_rms (using "stat.txt") >> plot2 >> 1D histogram of pedestal rms value >> plot3 >> rms value of pedestal pedestal for different channel within same PMT (for all PMT) 3) display3.pdf >> Equivalent to display1.pdf but using the file "range.txt" (which are extracted by fitting histogram in narrow rangel") 4) display4.pdf >> Equivalen to display2.pdf but using "rangle.txt" (fitted information) 5) display11.pdf >> plot1 >> xpixel:ypixel:Mean of Dark Current rate between 300 -500 (using "range.txt") >>plot2 >> 1D histogram of Mean of Dark Current for all 960 channel >> plot3>> Mean of Dark current of different pixel within a PMT 6) display12.pdf >> plot1 >> xpixel:ypixel:RMS of Dark Current rate between 300 -500 (using "range.txt") >>plot2 >> 1D histogram of RMS of Dark Current for all 960 channel >> plot3>> RMS Dark current of different pixel within a PMT 7) display15.pdf >> plot1 >> xpixel:ypixel:RMS/mean of Dark Current rate between 300 -500 (using "range.txt") >>plot2 >> 1D histogram of RMS/mean of Dark Current for all 960 channel >> plot3>> RMS/mean Dark current of different pixel within a PMT 8) display16.pdf >> plot1 >> xpixel:ypixel:RMS/sqrt(mean) of Dark Current rate between 300 -500 (using "range.txt") >>plot2 >> 1D histogram of RMS/sqrt(mean) of Dark Current for all 960 channel >> plot3>> RMS/sqrt(mean) Dark current of different pixel within a PMT #"*richDisplayScan.C*">> call a function display3 from "rich.C" * Output:* scan.pdf >> 1D and 2D plot are generated for each value of threshold between 200-300 >> Dark current is evaluated from 200 to next 300 in step of 1( for example dark current at 200, 201 202 ...) >> 2D histo >> xpixel:ypixel:Dark Current >> 1D histogram>> Dark current for given threshold ( for eg reading first plot : xaxis is dark current , most of the channel have dark current around 100. Y axis is count of number of channel have particular value of dark current # "doAnalysis.C" >> invokes the function doAnalysis( dark current run) or doPedestalAnalysis( pedestal run) from "rich.C" *output:* 1) ShowLargePedestal() >> largePedestals.pdf (if mean+10*sigma >Threshold) Then its large pedestal 2) DisplaySlopes() >> 1) slopeDisplay.pdf >> slope of dark current at 4 different points above threshold >> 2) slopeDisplay2.pdf>> slope of dark current of each pixel within a pmt. Red are slope with negative slope while blue a re +ve slope. Though in plot its plots the absolute value >> slopeHigh.txt >> if slope< -2 >> slopeVeryHigh.txt >> if slope < -10 3) DisplayRange() >> SPErange.pdf >> plot1 >> Maximum value if DAC unit (threshold) with count/rate>0 or last point of x-axis of hCount histogram. >> plot2 >> Maximum value of DAC unit with count>0, for different pixels in same pmt >> plot3>> pedestal mean with file "range.txt" i.e fitted value >> plot4 >> mean of the pedestal for each pixel in same pmt >> plot5>> RMS of the pedestal with file "range.txt" i.e fitted value >> plot6 >> RMS of the pedestal for each pixel in same pmt 4) DisplayRate() >> rate.pdf >> plot1 >> distribution of Dark current rate (between 300 -500) for NPIXEL*NPMT >> plot2 >> distribution of RMS of dark current (300-500) >> plot3>> distribution of RMS/Mean >> plot4>> Dark current rate mean for all pixel within same pmt >> plot5 >> Dark current RMS for all pixel within same PMT >> Plot6 >> Dark current RMS/Mean for all pixel within same pmt >> plot7 >> Dark current mean shoulder ( from Threshold + 25 )/ Dark current mean >> plot7 >> RMS Dark current shoulder ( from Threshold + 25 )/ Dark current RMS >> plot8 >> Mean Dark current shoulder ( from Threshold + 25 )/ Dark current mean for different pixel within same PMT >>plot9 >> RMS Dark current shoulder ( from Threshold + 25 )/ RMS Dark current for different pixel within same pmt 5) DisplayRatePMT() >> ratePMT.pdf >>plot1>> Mean Dark current rate for every PMT ("chiprate.pdf", dark current 300-500) average of 64 pixel >>plot2>> RMS Dark current rate for every PMT ("chiprate.pdf", dark current 300-500) average of 64 pixel >> plot3>> RMS/Mean of Dark current rate for every PMT ("chiprate.pdf", dark current 300-500) average of 64 pixe 6) DisplayHotPixels() >> hot.pdf >> pixels with dark current rate larger than 10 kHz 7) showThresholds() >> rateorderedRatio.txt >>Prints the slot, fiber, pmt,pixel, and (ShoulderMean/Mean) Dark Current if its greater than 2. In case of no cross-talk (ShoulderMean/Mean) Dark Current is ==1 . In other words shows possible cross-talk candidates. h1. Comparision between the pedestal or RMS between two runs at two different run period # Script is located at "/home/clasrun/rich/suite1.0/sw/ana/ped/comparePed.sh" in (solid@tunl11 machine) # Input of the script are the two directories where the pedestal files (""stat.txt) are located # compiles the script "richStability.C" from "/home/clasrun/rich/suite1.0/sw/ana/lib/" # Example of compilation: ./comparePed.sh <directory1> <directory2> # Output goes to directory "/home/clasrun/rich/suite1.0/results/scalers". Inside the folder "ped-<directory1>-<directory2>" # Contains the pdf file showing the comparsion of pedestals and rms between two runs
