/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57969.558521 0.000359 0.12059 0.02638 0.97581 0 3.94385 0.28189 3.25326 0.23252 0.47560 0.09832 0.39291 0.08123 57969.559221 0.000341 0.13150 0.02957 0.98305 0 3.62510 0.27886 2.97877 0.22914 0.47670 0.10074 0.39257 0.08295 57969.559892 0.000330 0.11380 0.02630 0.97368 0 4.15210 0.30302 3.40063 0.24817 0.47249 0.10360 0.38735 0.08493 57969.560754 0.000532 0.11909 0.02120 0.98370 0 4.06667 0.23819 3.31543 0.19417 0.48428 0.08140 0.39548 0.06648 57969.561900 0.000613 0.16529 0.02526 0.99057 0 3.51800 0.20376 2.88581 0.16713 0.58150 0.08224 0.47698 0.06746 57969.562867 0.000353 0.08665 0.02022 0.99180 0 4.65659 0.31051 3.81154 0.25413 0.40351 0.09024 0.33113 0.07404 57969.563787 0.000567 0.17862 0.02777 0.96939 0 3.56011 0.21599 2.92519 0.17745 0.63590 0.09103 0.52152 0.07466 57969.564814 0.000460 0.14251 0.02511 0.98069 0 4.03684 0.25596 3.33143 0.21122 0.57527 0.09458 0.47536 0.07815
