/* ** ** 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 56747.806350 0.000567 0.32329 0.02658 0.99490 0 7.01639 0.28560 6.29560 0.25621 2.26830 0.16203 2.03814 0.14560 56747.807548 0.000631 0.27465 0.02229 0.98165 0 7.47304 0.28065 6.73556 0.25294 2.05249 0.14765 1.84713 0.13287 56747.808838 0.000660 0.28469 0.02353 0.97807 0 6.86377 0.26313 6.14655 0.23563 1.95407 0.14306 1.74845 0.12796 56747.810132 0.000634 0.32161 0.02650 0.97717 0 6.44308 0.26093 5.78124 0.23410 2.07217 0.14867 1.85649 0.13320 56747.811396 0.000631 0.29541 0.02436 0.99083 0 6.81978 0.26888 6.15869 0.24283 2.01463 0.14595 1.82006 0.13182 56747.812652 0.000625 0.30071 0.02480 0.97685 0 6.84539 0.26986 6.18956 0.24400 2.05846 0.14909 1.86319 0.13495 56747.813902 0.000625 0.29910 0.02445 0.96759 0 7.03607 0.27311 6.32057 0.24533 2.10449 0.15140 1.89132 0.13605 56747.815158 0.000631 0.28721 0.02335 0.99083 0 7.07262 0.27129 6.38797 0.24501 2.03131 0.14563 1.83501 0.13154 56747.816567 0.000778 0.29421 0.02198 0.98141 0 6.83109 0.24002 6.17637 0.21701 2.00979 0.13251 1.81782 0.11985
