/* ** ** 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 58900.484609 0.001046 0.19289 0.04775 0.95833 1 2.91306 0.28601 0.58833 0.05775 0.56189 0.12768 0.11428 0.02595 58900.486439 0.000784 0.23624 0.05870 0.96296 1 3.20774 0.34758 0.65012 0.07045 0.75778 0.16945 0.15385 0.03440 58900.487862 0.000639 0.34271 0.08897 0.97727 1 2.67600 0.35297 0.54218 0.07152 0.91709 0.20507 0.18605 0.04160 58900.489431 0.000930 0.21379 0.05275 0.96875 1 2.98088 0.31085 0.60367 0.06295 0.63727 0.14250 0.12903 0.02885 58900.491334 0.000973 0.22212 0.05544 0.98507 1 2.67698 0.28724 0.54153 0.05810 0.59460 0.13398 0.12034 0.02712 58900.493353 0.001046 0.25355 0.05581 0.95562 1 2.94308 0.29407 0.59495 0.05945 0.74621 0.14635 0.15115 0.02964
