/* ** ** 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 56529.364318 0.000605 0.32972 0.02702 0.98565 0 6.75669 0.27581 5.90622 0.24108 2.22782 0.15829 1.94938 0.13849 56529.365498 0.000576 0.39041 0.03339 0.99497 0 5.80255 0.26240 5.08230 0.22982 2.26535 0.16444 1.98179 0.14385 56529.366676 0.000602 0.32311 0.02647 0.98558 0 6.84598 0.27762 6.01820 0.24405 2.21199 0.15743 1.94438 0.13839 56529.367880 0.000602 0.31291 0.02573 0.99519 0 6.96783 0.28009 6.15173 0.24728 2.18030 0.15641 1.92497 0.13809 56529.369092 0.000611 0.34282 0.02829 0.98578 0 6.32807 0.26427 5.58964 0.23343 2.16936 0.15440 1.91634 0.13639 56529.370252 0.000550 0.38928 0.03279 0.98421 0 6.18564 0.27647 5.46156 0.24411 2.40797 0.17194 2.12601 0.15181 56529.371410 0.000608 0.33528 0.02770 0.98571 0 6.52026 0.26981 5.75619 0.23819 2.18612 0.15632 1.92997 0.13800 56529.372587 0.000570 0.34182 0.02824 0.97462 0 6.85995 0.28510 6.05813 0.25178 2.34486 0.16743 2.07065 0.14785 56529.373739 0.000582 0.34218 0.02844 0.98010 0 6.64319 0.27739 5.86711 0.24498 2.27317 0.16338 2.00760 0.14429 56529.374911 0.000590 0.33293 0.02784 0.99020 0 6.60498 0.27432 5.83491 0.24233 2.19897 0.15961 1.94255 0.14100 56529.376282 0.000781 0.36647 0.02663 0.98889 0 6.12013 0.23086 5.40315 0.20382 2.24284 0.13929 1.98010 0.12297
