/* ** ** 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 56389.441465 0.001016 0.26757 0.02151 0.98291 0 4.91966 0.18166 4.30238 0.15885 1.31635 0.09401 1.15232 0.08229 56389.442793 0.000312 0.22215 0.03565 0.96296 0 4.83110 0.32986 4.23833 0.28941 1.07325 0.15586 0.94316 0.13694 56389.443985 0.000880 0.29275 0.02388 0.98026 0 5.21820 0.20115 4.53122 0.17466 1.52762 0.10981 1.32709 0.09539 56389.445779 0.000914 0.29299 0.02379 1.00000 0 4.90726 0.19163 4.30675 0.16816 1.43779 0.10234 1.26136 0.08978 56389.447671 0.000978 0.28708 0.02348 0.99408 0 4.68563 0.18053 4.09481 0.15774 1.34513 0.09703 1.17391 0.08466 56389.450359 0.001710 0.28958 0.01773 0.98308 0 4.80599 0.13870 4.18638 0.12081 1.39173 0.07517 1.21129 0.06542
