/* ** ** 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 59673.922050 0.000758 0.10776 0.00815 0.99237 0 15.23724 0.35833 14.12730 0.33223 1.64195 0.11809 1.52253 0.10949 59673.923523 0.000715 0.10869 0.00814 0.98785 0 16.22565 0.37967 15.05919 0.35237 1.76355 0.12543 1.63551 0.11630 59673.924883 0.000645 0.12391 0.00945 0.99552 0 15.50443 0.39346 14.39496 0.36530 1.92117 0.13815 1.78314 0.12823 59673.926173 0.000645 0.12552 0.00957 0.99103 0 15.36885 0.38973 14.26336 0.36170 1.92908 0.13872 1.79121 0.12881 59673.927452 0.000628 0.12770 0.00983 0.99539 0 15.40715 0.39600 14.30026 0.36754 1.96747 0.14271 1.82711 0.13253 59673.928714 0.000634 0.12509 0.00941 0.99087 0 15.87302 0.39745 14.77504 0.36996 1.98559 0.14084 1.84824 0.13109 59673.930638 0.001291 0.11340 0.00638 0.98655 0 15.62282 0.27796 14.47260 0.25747 1.77158 0.09461 1.64091 0.08764
