/* ** ** 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 57572.754175 0.000330 0.22514 0.03537 0.95614 0 4.79053 0.31925 4.05901 0.27048 1.07852 0.15342 0.91429 0.13004 57572.754821 0.000315 0.23191 0.03664 0.98165 0 4.70490 0.32378 4.02047 0.27668 1.09113 0.15520 0.93138 0.13248 57572.755550 0.000414 0.20233 0.03143 1.00000 0 4.05384 0.26072 3.45936 0.22249 0.82020 0.11600 0.70047 0.09906 57572.757104 0.001140 0.26005 0.02080 0.98223 0 4.62623 0.16799 3.96601 0.14402 1.20307 0.08571 1.03129 0.07347 57572.758579 0.000336 0.19528 0.03039 0.97414 0 5.32353 0.33419 4.55991 0.28626 1.03958 0.14806 0.89065 0.12685 57572.759722 0.000807 0.23194 0.02224 0.97849 0 4.98371 0.20631 4.27066 0.17679 1.15592 0.09996 0.99054 0.08566 57572.761840 0.001311 0.25441 0.01876 0.98455 0 4.79718 0.15881 4.11287 0.13615 1.22047 0.08040 1.04644 0.06893
