/* ** ** 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 56317.301233 0.001091 0.10906 0.00828 0.97878 0 11.14573 0.26278 9.81843 0.23149 1.21557 0.08769 1.07104 0.07725 56317.302906 0.000582 0.09420 0.01054 0.97300 0 11.04500 0.36210 9.69186 0.31772 1.04045 0.11132 0.91261 0.09762 56317.368828 0.001331 0.10591 0.00719 0.98482 0 11.56284 0.24406 10.10624 0.21330 1.22462 0.07899 1.07058 0.06905 56317.434568 0.000399 0.10529 0.01390 0.97826 0 11.06346 0.44436 9.22418 0.37042 1.16490 0.14649 0.97137 0.12218 56317.435274 0.000307 0.10568 0.01561 0.99057 0 11.11415 0.50719 9.30807 0.42476 1.17456 0.16497 0.98232 0.13793 56317.436521 0.000940 0.10757 0.00905 0.98462 0 10.85773 0.28414 9.19439 0.24060 1.16801 0.09339 0.98897 0.07907
