/* ** ** 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 59645.209591 0.000579 0.28958 0.02349 0.97000 0 8.12210 0.30888 7.07393 0.26897 2.35200 0.16851 2.04402 0.14643 59645.210696 0.000527 0.31139 0.02578 0.97802 0 8.10915 0.32556 7.10784 0.28535 2.52508 0.18280 2.21582 0.16040 59645.211842 0.000619 0.29164 0.02384 0.96262 0 7.57322 0.29155 6.56385 0.25266 2.20864 0.15926 1.91494 0.13808 59645.213016 0.000556 0.31794 0.02631 0.96875 0 7.60629 0.30555 6.65207 0.26721 2.41833 0.17494 2.11530 0.15302 59645.214148 0.000576 0.28344 0.02280 0.97487 0 8.46362 0.31943 7.30338 0.27562 2.39894 0.17043 2.06999 0.14706 59645.215383 0.000660 0.26035 0.02104 0.97807 0 7.82563 0.28552 6.79228 0.24779 2.03738 0.14691 1.76895 0.12755 59645.216642 0.000599 0.26768 0.02148 0.98551 0 8.33291 0.30859 7.29594 0.27016 2.23051 0.15875 1.95394 0.13906 59645.217906 0.000666 0.26113 0.02083 0.99565 0 7.66455 0.27899 6.70352 0.24401 2.00145 0.14209 1.74938 0.12419 59645.219319 0.000747 0.30086 0.02211 0.98837 0 7.38745 0.26217 6.41119 0.22752 2.22255 0.14301 1.92811 0.12405
