/* ** ** 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 56078.422492 0.000666 0.31248 0.02564 0.98696 0 6.17045 0.24661 5.58176 0.22307 1.92813 0.13820 1.74634 0.12516 56078.423739 0.000582 0.37186 0.03119 0.98507 0 6.03967 0.26302 5.39476 0.23490 2.24593 0.16097 2.00212 0.14349 56078.424943 0.000616 0.35421 0.02936 0.99061 0 6.00726 0.25491 5.33122 0.22622 2.12783 0.15148 1.88883 0.13446 56078.426103 0.000544 0.39732 0.03404 0.97340 0 6.01440 0.27248 5.40411 0.24484 2.38964 0.17377 2.14815 0.15618 56078.427324 0.000677 0.32204 0.02678 0.96154 0 6.08470 0.24627 5.41150 0.21902 1.95952 0.14236 1.74298 0.12662 56078.428606 0.000605 0.32749 0.02724 0.96651 0 6.69983 0.27368 5.96033 0.24347 2.19413 0.15901 1.95136 0.14139 56078.429752 0.000535 0.39195 0.03320 0.95135 0 6.42121 0.28474 5.71430 0.25339 2.51678 0.18161 2.24031 0.16165 56078.431462 0.001175 0.36548 0.02167 0.97291 0 6.15912 0.18818 5.46848 0.16708 2.25101 0.11442 1.99942 0.10163
