/* ** ** 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 56447.328314 0.000538 0.20171 0.03162 0.98387 0 3.11155 0.19851 2.67232 0.17047 0.62763 0.08986 0.54145 0.07752 56447.329416 0.000564 0.19386 0.02998 0.97436 0 3.13475 0.19595 2.71974 0.17001 0.60771 0.08594 0.52719 0.07456 56447.330516 0.000535 0.22865 0.03610 0.97838 0 2.78860 0.19083 2.41038 0.16495 0.63761 0.09073 0.55042 0.07832 56447.331589 0.000538 0.21637 0.03393 0.96237 0 2.98780 0.19663 2.57502 0.16944 0.64647 0.09200 0.55657 0.07920 56447.332703 0.000576 0.18923 0.02938 0.97487 0 3.13829 0.19496 2.71792 0.16884 0.59386 0.08450 0.51354 0.07307 56447.333595 0.000315 0.14917 0.03737 0.97248 0 2.80119 0.24841 2.43101 0.21558 0.41785 0.09789 0.36270 0.08498 56447.334492 0.000582 0.19209 0.03035 0.97512 0 3.00828 0.18916 2.60640 0.16389 0.57785 0.08377 0.50003 0.07248 56447.335643 0.000570 0.22228 0.03479 0.96447 0 2.72642 0.18285 2.37079 0.15900 0.60603 0.08571 0.52719 0.07456 56447.337052 0.000839 0.16740 0.02300 0.96897 0 3.05105 0.15973 2.64457 0.13844 0.51074 0.06487 0.44202 0.05614
