/* ** ** 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 60006.310059 0.000330 0.15805 0.01237 1.00000 0 24.41198 0.69825 21.83167 0.62440 3.85835 0.28111 3.45409 0.25158 60006.310675 0.000286 0.19762 0.01551 1.00000 0 22.60849 0.71978 20.43993 0.65073 4.46790 0.32041 4.03365 0.28929 60006.311295 0.000333 0.16551 0.01268 1.00000 0 23.89674 0.70039 21.17170 0.62050 3.95517 0.28003 3.50342 0.24807 60006.311989 0.000362 0.15417 0.01179 0.97600 0 23.88416 0.66877 21.18760 0.59325 3.68213 0.26207 3.26956 0.23268 60006.312652 0.000301 0.16525 0.01287 1.00000 0 26.22414 0.76683 23.13237 0.67642 4.33359 0.31279 3.82260 0.27591 60006.313285 0.000333 0.16916 0.01308 0.99130 0 23.36135 0.69187 20.70507 0.61322 3.95179 0.28232 3.50096 0.25012 60006.313933 0.000315 0.17544 0.01353 0.97248 0 24.26809 0.72256 21.44105 0.63839 4.25764 0.30301 3.76308 0.26781 60006.314599 0.000350 0.15961 0.01236 0.99174 0 23.18382 0.66860 20.72895 0.59774 3.70044 0.26606 3.31107 0.23808 60006.315265 0.000315 0.17686 0.01372 0.99083 0 23.41181 0.70633 20.90311 0.63053 4.14050 0.29587 3.69545 0.26402 60006.315944 0.000365 0.14084 0.01104 1.00000 0 24.51045 0.67116 21.94765 0.60103 3.45202 0.25363 3.09510 0.22750 60006.316668 0.000359 0.15894 0.01220 0.99194 0 23.25751 0.66221 20.51835 0.58422 3.69647 0.26342 3.26108 0.23239 60006.317359 0.000333 0.16124 0.01254 1.00000 0 24.05058 0.69664 21.43725 0.62091 3.87803 0.27995 3.45696 0.24952 60006.318071 0.000379 0.14139 0.01089 0.99237 0 24.35955 0.66103 21.50589 0.58359 3.44425 0.24830 3.04096 0.21922 60006.318780 0.000330 0.15988 0.01242 1.00000 0 24.40524 0.70655 21.70181 0.62831 3.90202 0.28131 3.46776 0.24999 60006.319434 0.000324 0.17574 0.01359 0.99107 0 23.22674 0.69733 20.55675 0.61713 4.08182 0.29090 3.61362 0.25751 60006.320094 0.000336 0.16380 0.01253 1.00000 0 23.74786 0.69387 21.09018 0.61614 3.89002 0.27507 3.45403 0.24424 60006.320774 0.000344 0.15984 0.01244 0.99160 0 23.34519 0.67009 20.97466 0.60199 3.73142 0.27001 3.35210 0.24258 60006.321668 0.000550 0.15450 0.00963 0.98947 0 23.66932 0.53434 21.23936 0.47942 3.65680 0.21236 3.27969 0.19048
