/* ** ** 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 55215.262763 0.000515 0.31497 0.01162 1.00000 0 38.87246 0.69978 35.27746 0.63503 12.24365 0.39427 11.11544 0.35795 55215.263781 0.000503 0.30302 0.01109 1.00000 0 41.32158 0.72872 37.65282 0.66402 12.52119 0.40168 11.40965 0.36602 55215.264780 0.000495 0.31749 0.01173 1.00000 0 39.98574 0.72513 36.43588 0.66075 12.69527 0.40858 11.56795 0.37230 55215.265749 0.000475 0.32631 0.01206 1.00000 0 40.82678 0.74617 37.20452 0.67997 13.32199 0.42793 12.14021 0.38997 55215.266698 0.000475 0.32860 0.01209 1.00000 0 40.54922 0.74300 36.94823 0.67702 13.32429 0.42532 12.14119 0.38755 55215.267641 0.000469 0.32951 0.01222 1.00000 0 40.66044 0.74928 37.05698 0.68288 13.39785 0.43120 12.21062 0.39299 55215.268596 0.000486 0.32063 0.01175 1.00000 0 40.73145 0.73569 37.12145 0.67049 13.05975 0.41627 11.90236 0.37938 55215.269568 0.000486 0.31354 0.01146 1.00000 0 41.58028 0.74534 37.89847 0.67934 13.03721 0.41503 11.88280 0.37828 55215.270549 0.000495 0.31295 0.01147 1.00000 0 40.79851 0.73048 37.18599 0.66580 12.76802 0.40825 11.63747 0.37210 55215.271620 0.000576 0.32433 0.01070 1.00000 0 41.96796 0.68648 38.25170 0.62569 13.61133 0.39016 12.40605 0.35561
