/* ** ** 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 57908.096106 0.000356 0.15045 0.03714 0.92683 0 2.72789 0.24128 2.27484 0.20120 0.41041 0.09459 0.34236 0.07885 57908.097139 0.000677 0.18535 0.02957 0.93590 0 2.84832 0.17974 2.38604 0.15056 0.52792 0.07737 0.44317 0.06494 57908.098259 0.000443 0.15444 0.03092 0.95425 0 3.05986 0.22889 2.57706 0.19277 0.47256 0.08775 0.39792 0.07389 57908.099054 0.000353 0.17562 0.04077 0.95082 0 2.62277 0.23640 2.21050 0.19924 0.46062 0.09855 0.38827 0.08307 57908.099810 0.000402 0.13350 0.03175 0.95683 0 2.67635 0.21693 2.25608 0.18286 0.35730 0.07989 0.30125 0.06736 57908.100527 0.000315 0.16592 0.03973 0.97248 0 2.80396 0.25648 2.36211 0.21606 0.46524 0.10296 0.39199 0.08675 57908.101143 0.000301 0.16385 0.03974 1.00000 0 2.80061 0.26305 2.34589 0.22032 0.45889 0.10261 0.38526 0.08615 57908.101803 0.000359 0.15526 0.03775 0.91935 0 2.65065 0.23150 2.23406 0.19512 0.41153 0.09338 0.34691 0.07872 57908.102680 0.000518 0.09192 0.02244 0.98883 0 2.81236 0.19730 2.36291 0.16576 0.25853 0.06044 0.21757 0.05087 57908.103499 0.000301 0.19547 0.04843 0.97115 0 2.37345 0.23617 2.00334 0.19934 0.46395 0.10528 0.39156 0.08885 57908.104260 0.000460 0.10490 0.02502 0.97484 0 2.88523 0.21159 2.43227 0.17838 0.30265 0.06868 0.25515 0.05790 57908.105466 0.000747 0.15976 0.02629 0.98062 0 2.56165 0.15659 2.15558 0.13177 0.40925 0.06253 0.34430 0.05260
