/* ** ** 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 58234.167876 0.000547 0.14994 0.03659 0.96825 0 1.66237 0.14928 1.43902 0.12922 0.24925 0.05657 0.21608 0.04904 58234.168860 0.000437 0.18176 0.04503 0.98013 0 1.70023 0.16903 1.47264 0.14640 0.30903 0.07013 0.26718 0.06064 58234.169771 0.000475 0.15705 0.03842 0.97561 0 1.83174 0.16739 1.57499 0.14393 0.28768 0.06529 0.24714 0.05609 58234.170888 0.000642 0.12602 0.02998 0.96847 0 1.71135 0.13876 1.46832 0.11904 0.21567 0.04823 0.18636 0.04167 58234.172089 0.000553 0.13650 0.03258 0.95288 0 1.87032 0.15616 1.60964 0.13438 0.25530 0.05709 0.22015 0.04923 58234.173243 0.000602 0.14387 0.03450 0.96154 0 1.62571 0.14061 1.39666 0.12077 0.23390 0.05230 0.20033 0.04480 58234.174612 0.000767 0.10844 0.02586 0.94340 0 1.68754 0.12386 1.45732 0.10696 0.18299 0.04153 0.15817 0.03590 58234.175917 0.000538 0.13944 0.03424 0.96237 0 1.83031 0.15580 1.57013 0.13366 0.25523 0.05878 0.21798 0.05022 58234.177442 0.000987 0.12667 0.02382 0.98534 0 1.74904 0.11191 1.50862 0.09651 0.22156 0.03917 0.19079 0.03373
