/* ** ** 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 56061.295561 0.000781 0.33271 0.02728 0.98148 0 5.35745 0.21939 4.55520 0.18654 1.78249 0.12660 1.51514 0.10761 56061.297213 0.000871 0.30100 0.02456 0.98671 0 5.17929 0.20326 4.43763 0.17415 1.55896 0.11155 1.33574 0.09558 56061.299010 0.000926 0.32406 0.02383 0.97273 0 5.75973 0.20772 4.93445 0.17796 1.86647 0.11959 1.59899 0.10245 56061.361804 0.000787 0.31571 0.02620 0.97426 0 5.21537 0.20883 4.71344 0.18873 1.64656 0.11967 1.48804 0.10815 56061.363341 0.000749 0.33617 0.02784 0.99228 0 5.09952 0.21203 4.58701 0.19072 1.71432 0.12281 1.54292 0.11053 56061.365381 0.001291 0.29368 0.01920 0.98655 0 5.28331 0.16500 4.77359 0.14908 1.55159 0.08910 1.40189 0.08050
