/* ** ** 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 54586.363148 0.000637 0.26307 0.02868 0.98636 0 4.41092 0.21911 3.75700 0.18661 1.16037 0.11261 0.98962 0.09604 54586.364771 0.000987 0.29545 0.02411 0.98534 0 4.68407 0.18167 3.98079 0.15438 1.38391 0.09938 1.17646 0.08447 54586.366065 0.000307 0.22578 0.03540 0.99057 0 4.97014 0.33665 4.23124 0.28660 1.12215 0.15870 0.95397 0.13491 54586.366690 0.000318 0.26076 0.04163 0.96364 0 4.20715 0.30444 3.60445 0.26083 1.09706 0.15610 0.93990 0.13374 54586.367361 0.000353 0.22741 0.03553 0.99180 0 4.32179 0.29207 3.68377 0.24894 0.98281 0.13845 0.83994 0.11832 54586.368067 0.000347 0.21233 0.03368 0.99167 0 4.57463 0.30394 3.89776 0.25895 0.97134 0.13992 0.82818 0.11930 54586.369161 0.000747 0.24144 0.02421 0.98062 0 4.77879 0.21154 4.09666 0.18135 1.15379 0.10379 0.98921 0.08898 54586.370272 0.000365 0.18233 0.02810 0.99206 0 5.17723 0.31348 4.43586 0.26859 0.94394 0.13377 0.80876 0.11461 54586.371776 0.001140 0.28586 0.02293 0.97716 0 4.25685 0.16119 3.64132 0.13788 1.21688 0.08605 1.04069 0.07359 54586.373267 0.000350 0.21611 0.03392 0.98347 0 4.51810 0.29937 3.87404 0.25670 0.97642 0.13893 0.83722 0.11913 54586.374308 0.000692 0.26373 0.02673 0.98745 0 4.69405 0.21728 4.01039 0.18563 1.23795 0.11163 1.05819 0.09542
