/* ** ** 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 56745.466631 0.000631 0.29252 0.02386 0.98624 0 7.18856 0.27715 6.28341 0.24222 2.10283 0.15118 1.83945 0.13221 56745.467834 0.000573 0.32455 0.02649 0.98990 0 7.25171 0.29412 6.32432 0.25650 2.35352 0.16669 2.05408 0.14546 56745.469012 0.000605 0.30299 0.02488 1.00000 0 7.13269 0.28302 6.24307 0.24773 2.16112 0.15533 1.89225 0.13601 56745.470271 0.000654 0.28470 0.02292 0.98230 0 7.21467 0.27442 6.31785 0.24031 2.05402 0.14572 1.80013 0.12770 56745.471570 0.000645 0.29045 0.02377 0.98655 0 7.07190 0.27333 6.17391 0.23860 2.05404 0.14813 1.79293 0.12930 56745.472904 0.000689 0.28384 0.02306 0.97059 0 6.91940 0.26207 6.02935 0.22835 1.96402 0.14116 1.71204 0.12306 56745.474215 0.000622 0.30722 0.02518 0.97674 0 7.07590 0.28085 6.15751 0.24440 2.17383 0.15586 1.89278 0.13570 56745.475378 0.000541 0.32920 0.02735 0.97861 0 7.46510 0.30494 6.53066 0.26676 2.45747 0.17780 2.14976 0.15554 56745.476544 0.000625 0.29261 0.02356 0.97222 0 7.55309 0.29021 6.53757 0.25117 2.21013 0.15640 1.91254 0.13534 56745.477800 0.000631 0.32727 0.02597 0.97706 0 7.10296 0.27980 6.14071 0.24188 2.32457 0.16011 2.01207 0.13857
