/* ** ** 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 56836.982666 0.000576 0.26044 0.02094 0.98492 0 8.76694 0.31938 7.77263 0.28313 2.28327 0.16367 2.02810 0.14539 56836.983731 0.000489 0.30314 0.02468 1.00000 0 8.91913 0.35246 7.78385 0.30757 2.70379 0.19245 2.35859 0.16786 56836.984677 0.000457 0.33160 0.02757 0.99367 0 8.65178 0.35821 7.57058 0.31346 2.86892 0.20689 2.51257 0.18117 56836.985603 0.000469 0.33173 0.02732 0.98148 0 8.67717 0.35617 7.53745 0.30939 2.87849 0.20553 2.50044 0.17854 56836.986590 0.000518 0.29263 0.02372 0.97207 0 8.94543 0.34299 7.80220 0.29915 2.61773 0.18693 2.28489 0.16315 56836.987554 0.000446 0.35397 0.02955 0.97403 0 8.46028 0.35951 7.43995 0.31617 2.99465 0.21523 2.63670 0.18950 56836.988546 0.000547 0.26868 0.02166 0.97354 0 9.23382 0.33940 8.05786 0.29619 2.48092 0.17798 2.16565 0.15535 56836.989686 0.000593 0.25043 0.02008 0.98537 0 8.98569 0.32289 7.85612 0.28228 2.25027 0.16130 1.96786 0.14107 56836.990794 0.000515 0.29223 0.02361 0.97191 0 9.06624 0.34597 7.90322 0.30158 2.64939 0.18870 2.30967 0.16450 56836.991764 0.000454 0.34093 0.02830 0.99363 0 8.54192 0.35749 7.47123 0.31265 2.91223 0.20879 2.54813 0.18267 56836.992727 0.000509 0.31584 0.02577 0.97159 0 8.43724 0.33662 7.38286 0.29455 2.66485 0.18968 2.33101 0.16590 56836.993749 0.000512 0.29558 0.02404 0.98305 0 8.89776 0.34616 7.72954 0.30072 2.63004 0.18779 2.28489 0.16315 56836.994828 0.000567 0.26833 0.02160 0.96939 0 8.94869 0.32650 7.82124 0.28535 2.40117 0.17227 2.09726 0.15045 56836.995884 0.000489 0.33808 0.02802 0.97041 0 8.19931 0.33784 7.15221 0.29469 2.77200 0.19936 2.41754 0.17387 56836.996874 0.000501 0.28533 0.02331 0.99422 0 9.21716 0.35459 8.03907 0.30927 2.62992 0.18959 2.29345 0.16537 56836.997854 0.000480 0.34900 0.02889 0.98193 0 8.12224 0.34109 7.05791 0.29639 2.83467 0.20217 2.46328 0.17568 56836.999151 0.000816 0.32136 0.02034 0.98227 0 8.63509 0.26826 7.51880 0.23357 2.77501 0.15299 2.41841 0.13333
