/* ** ** 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 57898.340714 0.000350 0.18821 0.04284 0.95868 0 2.47661 0.22603 2.10392 0.19200 0.46613 0.09720 0.39721 0.08282 57898.341486 0.000422 0.13588 0.03234 0.94521 0 2.52492 0.20551 2.13864 0.17405 0.34308 0.07672 0.29034 0.06492 57898.342302 0.000394 0.12920 0.03073 0.98529 0 2.71029 0.21971 2.30753 0.18705 0.35017 0.07830 0.29901 0.06686 57898.343269 0.000573 0.09204 0.02152 0.94949 0 2.72899 0.18649 2.32144 0.15861 0.25119 0.05617 0.21312 0.04766 57898.344221 0.000379 0.12377 0.02943 0.98473 0 2.96746 0.24005 2.51266 0.20327 0.36728 0.08213 0.31059 0.06945 57898.344993 0.000394 0.10738 0.02606 0.97059 0 3.20098 0.24253 2.75091 0.20843 0.34373 0.07926 0.29539 0.06812 57898.345728 0.000341 0.14166 0.03441 0.97458 0 2.84424 0.24550 2.43408 0.21010 0.40293 0.09148 0.34373 0.07805 57898.346449 0.000379 0.14345 0.03350 0.93893 0 2.79468 0.23257 2.37272 0.19746 0.40089 0.08749 0.34203 0.07464 57898.347464 0.000637 0.20350 0.03199 0.95455 0 2.71654 0.17620 2.31754 0.15030 0.55282 0.07915 0.47186 0.06755 57898.348604 0.000503 0.13220 0.03152 0.97126 0 2.08939 0.17294 1.78198 0.14749 0.27621 0.06176 0.23708 0.05301 57898.349403 0.000295 0.16381 0.03962 0.99020 0 2.81770 0.25963 2.42165 0.22313 0.46158 0.10321 0.39670 0.08870 57898.350054 0.000356 0.14722 0.03540 0.97561 0 2.63877 0.23324 2.26786 0.20045 0.38848 0.08687 0.33389 0.07466 57898.350879 0.000469 0.14382 0.02992 0.95679 0 2.79406 0.20519 2.40283 0.17646 0.40184 0.07822 0.34550 0.06725
