/* ** ** 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 59661.197119 0.000527 0.31151 0.02543 0.97802 0 8.06172 0.32127 7.19604 0.28678 2.51130 0.17890 2.24464 0.15988 59661.198279 0.000634 0.28094 0.02278 0.98174 0 7.32289 0.27717 6.58459 0.24922 2.05726 0.14750 1.84867 0.13255 59661.199567 0.000654 0.26613 0.02165 0.99558 0 7.37726 0.27403 6.57991 0.24440 1.96330 0.14206 1.74835 0.12651 59661.200785 0.000564 0.31371 0.02576 0.97949 0 7.38149 0.29539 6.63409 0.26548 2.31565 0.16602 2.08096 0.14920 59661.202764 0.001415 0.23586 0.01333 0.98744 0 7.67746 0.18911 6.90966 0.17020 1.81082 0.09210 1.62987 0.08289 59661.263211 0.000590 0.28970 0.02379 0.98039 0 7.61752 0.29652 6.78494 0.26412 2.20680 0.15959 1.96765 0.14230 59661.264432 0.000631 0.26864 0.02188 0.99083 0 7.60769 0.28472 6.78319 0.25388 2.04370 0.14781 1.82190 0.13176 59661.265586 0.000524 0.31240 0.02578 1.00000 0 7.92714 0.32123 7.00938 0.28401 2.47646 0.17807 2.19090 0.15752 59661.266692 0.000582 0.29617 0.02451 0.99005 0 7.49627 0.29760 6.67472 0.26496 2.22014 0.16124 1.97736 0.14355 59661.267829 0.000556 0.29917 0.02422 0.97917 0 8.00392 0.31221 7.10450 0.27710 2.39455 0.16986 2.12578 0.15080 59661.269258 0.000874 0.29817 0.01998 0.99007 0 7.55000 0.24461 6.67395 0.21622 2.25118 0.13204 1.99275 0.11688
