/* ** ** 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 59730.957881 0.000645 0.24591 0.01981 0.98655 0 8.02187 0.28735 7.28040 0.26074 1.97269 0.14234 1.79234 0.12932 59730.959183 0.000657 0.25428 0.02051 0.98678 0 7.73738 0.28209 6.96724 0.25398 1.96750 0.14158 1.76928 0.12732 59730.960474 0.000634 0.26181 0.02110 0.98630 0 7.79252 0.28617 7.01921 0.25779 2.04014 0.14635 1.83971 0.13195 59730.961782 0.000674 0.25491 0.02037 0.97854 0 7.60845 0.27636 6.85060 0.24881 1.93950 0.13808 1.74802 0.12443 59730.963159 0.000703 0.22895 0.01826 0.99177 0 7.96711 0.27527 7.17382 0.24787 1.82410 0.13114 1.64055 0.11797 59730.964519 0.000657 0.23264 0.01842 0.99119 0 8.41606 0.29148 7.61422 0.26366 1.95791 0.13937 1.77133 0.12609 59730.965885 0.000709 0.22439 0.01790 0.97959 0 8.06417 0.27485 7.32497 0.24962 1.80951 0.13055 1.64298 0.11854 59730.967320 0.000726 0.23473 0.01804 0.97211 0 8.32843 0.27648 7.52176 0.24968 1.95496 0.13550 1.76723 0.12247
