/* ** ** 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 56027.548407 0.000845 0.28349 0.02329 0.98630 0 5.62220 0.21594 4.81182 0.18478 1.59384 0.11575 1.36234 0.09890 56027.550161 0.000909 0.25681 0.02089 0.96497 0 5.93023 0.21488 5.03110 0.18228 1.52295 0.11094 1.29147 0.09407 56027.551897 0.000828 0.29832 0.02439 0.97203 0 5.56500 0.21693 4.76810 0.18587 1.66015 0.11933 1.42256 0.10225 56027.553616 0.000891 0.26530 0.02156 0.97403 0 5.78559 0.21276 4.96976 0.18276 1.53493 0.11121 1.31774 0.09548 56027.555314 0.000807 0.28018 0.02279 0.96057 0 6.12433 0.23011 5.25113 0.19729 1.71589 0.12376 1.47176 0.10614 56027.557568 0.001447 0.31239 0.01843 0.98600 0 5.84006 0.16854 4.98962 0.14400 1.82439 0.09385 1.55784 0.08013
