/* ** ** 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 58017.717042 0.000315 0.15431 0.03771 0.99083 0 2.74132 0.24690 2.36894 0.21337 0.42301 0.09609 0.36587 0.08311 58017.717684 0.000327 0.23694 0.05727 0.98230 0 1.91048 0.20619 1.65537 0.17865 0.45268 0.09791 0.39208 0.08480 58017.718651 0.000639 0.21067 0.03330 0.98190 0 2.52433 0.16901 2.17554 0.14563 0.53179 0.07616 0.45650 0.06538 58017.719719 0.000428 0.12630 0.03006 0.97973 0 2.54592 0.20775 2.19501 0.17913 0.32154 0.07190 0.27632 0.06179 58017.720485 0.000339 0.15777 0.03865 0.99145 0 2.49210 0.22840 2.15922 0.19790 0.39319 0.08932 0.34064 0.07738 58017.721304 0.000480 0.17641 0.03455 0.96988 0 2.56756 0.19606 2.21361 0.16900 0.45295 0.08170 0.39131 0.07056 58017.722303 0.000518 0.17581 0.03411 0.95828 0 2.43255 0.18464 2.10634 0.15988 0.42766 0.07635 0.37051 0.06614
