/* ** ** 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 54592.395886 0.000350 0.22466 0.03601 0.97521 0 4.46527 0.30630 3.70052 0.25383 1.00317 0.14531 0.83109 0.12038 54592.397373 0.001137 0.29935 0.02432 0.97455 0 4.21041 0.16344 3.46158 0.13436 1.26040 0.08994 1.03791 0.07405 54592.398823 0.000312 0.23269 0.03702 0.98148 0 4.90874 0.34112 4.01396 0.27890 1.14222 0.16347 0.93507 0.13382 54592.400191 0.001056 0.32264 0.02656 0.96712 0 4.22518 0.17122 3.47002 0.14060 1.36323 0.09771 1.12166 0.08038 54592.401583 0.000336 0.23901 0.03782 0.96552 0 4.53207 0.31375 3.72218 0.25769 1.08323 0.15411 0.88966 0.12657 54592.402246 0.000327 0.26875 0.04146 0.96460 0 4.45845 0.31776 3.66054 0.26088 1.19821 0.16395 0.98767 0.13514 54592.402955 0.000382 0.27731 0.03974 0.97727 0 4.26149 0.28486 3.54598 0.23703 1.18175 0.14981 0.98171 0.12444 54592.403669 0.000333 0.24289 0.03758 0.97391 0 4.64815 0.31891 3.83548 0.26313 1.12899 0.15658 0.93012 0.12898 54592.404320 0.000318 0.28367 0.04607 0.97273 0 3.95672 0.30359 3.25386 0.24964 1.12241 0.16066 0.92634 0.13257 54592.404960 0.000321 0.29465 0.04729 0.94595 0 3.97480 0.30427 3.32273 0.25433 1.17116 0.16522 0.97714 0.13786 54592.405660 0.000379 0.20109 0.03175 0.98473 0 4.55670 0.29519 3.80012 0.24617 0.91633 0.13194 0.76429 0.11004 54592.406479 0.000440 0.27570 0.03584 0.97368 0 4.50413 0.27059 3.74466 0.22495 1.24181 0.14318 1.03164 0.11894
