/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 59198.182452 0.000466 0.16568 0.01305 0.98758 0 16.45061 0.48256 14.86439 0.43603 2.72553 0.19929 2.46220 0.18005 59198.183390 0.000472 0.15160 0.01167 1.00000 0 17.89584 0.50245 16.07005 0.45118 2.71297 0.19441 2.43556 0.17454 59198.184339 0.000477 0.15470 0.01200 0.99394 0 17.22602 0.49033 15.57483 0.44333 2.66494 0.19227 2.40951 0.17384 59198.185288 0.000472 0.15967 0.01245 0.99387 0 16.98662 0.49098 15.28379 0.44179 2.71227 0.19647 2.44030 0.17678 59198.186202 0.000443 0.16986 0.01343 0.98693 0 16.92711 0.50840 15.25472 0.45815 2.87528 0.21023 2.59264 0.18958 59198.187145 0.000501 0.15877 0.01246 0.97110 0 16.31735 0.47196 14.75248 0.42669 2.59066 0.18894 2.34222 0.17082 59198.188115 0.000469 0.15381 0.01208 0.98765 0 17.65447 0.50676 15.89208 0.45615 2.71545 0.19859 2.44681 0.17892 59198.188997 0.000414 0.18511 0.01464 0.98601 0 16.66717 0.52075 15.06984 0.47084 3.08524 0.22409 2.78954 0.20261 59198.189816 0.000405 0.17975 0.01427 0.99286 0 17.32928 0.53649 15.66892 0.48509 3.11490 0.22777 2.81647 0.20595 59198.190693 0.000472 0.15354 0.01174 0.97546 0 18.06888 0.50531 16.33699 0.45688 2.77428 0.19749 2.50837 0.17856 59198.191752 0.000587 0.16244 0.01142 0.97044 0 16.91044 0.44232 15.24090 0.39865 2.74693 0.17920 2.47538 0.16149
