/* ** ** 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 58607.194092 0.000367 0.14653 0.03568 0.98425 0 2.54663 0.22263 2.15983 0.18881 0.37315 0.08480 0.31607 0.07181 58607.194784 0.000324 0.17780 0.04323 0.98214 0 2.38182 0.22737 2.04866 0.19557 0.42348 0.09469 0.36424 0.08145 58607.195406 0.000298 0.17798 0.04387 0.98058 0 2.55388 0.24408 2.19944 0.21020 0.45453 0.10327 0.39118 0.08888 58607.196190 0.000486 0.13602 0.03295 0.98214 0 2.05502 0.17265 1.76315 0.14809 0.27953 0.06351 0.23945 0.05440 58607.197078 0.000402 0.13191 0.03189 0.99281 0 2.51716 0.20816 2.16902 0.17937 0.33205 0.07544 0.28630 0.06505 58607.197998 0.000518 0.10071 0.02399 0.97207 0 2.61874 0.18725 2.25435 0.16119 0.26373 0.05992 0.22706 0.05159 58607.198884 0.000367 0.14404 0.03446 0.96063 0 2.65842 0.22581 2.27883 0.19356 0.38291 0.08563 0.32842 0.07344 58607.199607 0.000350 0.16348 0.04003 0.95868 0 2.41564 0.22065 2.08225 0.19020 0.39491 0.08973 0.34060 0.07738
