/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 56499.611340 0.000645 0.33612 0.02790 0.99103 0 6.37475 0.26669 5.36465 0.22437 2.14268 0.15364 1.79864 0.12894 56499.612517 0.000532 0.40427 0.03449 0.97826 0 6.41375 0.29264 5.42378 0.24742 2.59286 0.18695 2.19146 0.15802 56499.613576 0.000527 0.39645 0.03349 0.97253 0 6.68843 0.29921 5.65745 0.25304 2.65161 0.18997 2.24029 0.16049 56499.614716 0.000613 0.36601 0.03052 0.99057 0 6.11003 0.26550 5.18814 0.22541 2.23631 0.15917 1.89809 0.13509 56499.615883 0.000553 0.42640 0.03650 0.99476 0 5.86518 0.27556 4.94200 0.23218 2.50091 0.17896 2.10775 0.15082 56499.617052 0.000616 0.36999 0.03100 0.96714 0 6.14138 0.26672 5.20700 0.22613 2.27226 0.16282 1.92491 0.13790 56499.618186 0.000518 0.43292 0.03732 0.99441 0 6.01971 0.28638 5.13010 0.24406 2.60605 0.18734 2.22189 0.15969 56499.619256 0.000553 0.38326 0.03221 0.98953 0 6.43711 0.28534 5.48043 0.24291 2.46708 0.17616 2.10352 0.15020 56499.620359 0.000550 0.44154 0.03781 0.99474 0 5.65267 0.26841 4.79959 0.22788 2.49589 0.17789 2.11925 0.15105 56499.621904 0.000995 0.43487 0.02692 0.98256 0 6.09523 0.20836 5.20810 0.17802 2.65062 0.13679 2.26623 0.11696
