/* ** ** 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 59663.110337 0.000697 0.26978 0.02178 0.97925 0 8.17049 0.30134 6.21620 0.22897 2.20427 0.15831 1.68442 0.12074 59663.111723 0.000689 0.27670 0.02257 0.97479 0 7.70367 0.29348 6.14247 0.23400 2.13164 0.15370 1.70039 0.12260 59663.113059 0.000648 0.27635 0.02268 0.97768 0 8.05193 0.30419 6.48088 0.24483 2.22516 0.16213 1.79167 0.13054 59663.114431 0.000723 0.24140 0.01956 0.98400 0 8.21365 0.29204 6.59195 0.23436 1.98281 0.14440 1.59106 0.11585 59663.115710 0.000556 0.34059 0.02812 0.99479 0 7.75533 0.32698 6.15352 0.25943 2.64137 0.18754 2.09744 0.14890 59663.116925 0.000660 0.29330 0.02438 0.97807 0 7.37153 0.28900 5.95313 0.23340 2.16207 0.15847 1.74593 0.12797 59663.118499 0.000909 0.30054 0.02106 0.98408 0 7.27425 0.24710 5.84693 0.19861 2.18618 0.13395 1.75643 0.10763
