/* ** ** 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 54589.118033 0.000307 0.18895 0.04693 0.95283 0 3.37800 0.32954 2.15360 0.20842 0.63827 0.14578 0.39152 0.08886 54589.119003 0.000663 0.26894 0.04686 0.94323 0 2.91309 0.23366 1.48274 0.11887 0.78345 0.12117 0.39397 0.06091 54589.119975 0.000310 0.33329 0.08807 0.98131 0 2.14832 0.29059 1.13231 0.15314 0.71601 0.16254 0.37661 0.08547 54589.120921 0.000637 0.30957 0.05086 0.96364 0 2.90379 0.23424 1.50795 0.12162 0.89894 0.12866 0.46755 0.06691 54589.121922 0.000365 0.16674 0.04044 0.99206 0 3.77762 0.35398 1.96420 0.18391 0.62989 0.14091 0.32053 0.07167 54589.123007 0.000720 0.28683 0.04688 0.96386 0 2.77315 0.21463 1.43810 0.11126 0.79541 0.11450 0.41083 0.05914 54589.124078 0.000350 0.26678 0.06705 0.94215 0 2.49402 0.28586 1.31906 0.15122 0.66535 0.14881 0.35146 0.07859 54589.124801 0.000373 0.18973 0.04965 0.94574 0 3.20941 0.32666 1.61768 0.16456 0.60892 0.14681 0.30699 0.07406 54589.125860 0.000686 0.32568 0.05372 0.97046 0 2.55233 0.20902 1.32895 0.10875 0.83125 0.11902 0.43096 0.06167 54589.126902 0.000356 0.21108 0.05264 0.93496 0 3.15629 0.32593 1.63165 0.16845 0.66625 0.15122 0.34386 0.07804 54589.127912 0.000654 0.26387 0.04261 0.97788 0 3.18890 0.23842 1.70399 0.12740 0.84147 0.12043 0.44851 0.06419 54589.129214 0.000648 0.28094 0.04644 0.96875 0 2.91914 0.22527 1.56662 0.12084 0.82011 0.11988 0.43831 0.06405
