/* ** ** 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 58259.022351 0.000515 0.11933 0.02827 0.98315 0 2.27629 0.17813 1.92421 0.15058 0.27163 0.06074 0.22895 0.05120 58259.023268 0.000402 0.14433 0.03503 0.97122 0 2.38526 0.20524 2.02850 0.17454 0.34427 0.07813 0.29292 0.06648 58259.024055 0.000385 0.16822 0.04129 0.96241 0 2.15540 0.20143 1.83668 0.17165 0.36258 0.08229 0.30894 0.07011 58259.024889 0.000443 0.13899 0.03362 0.96078 0 2.27091 0.19014 1.93553 0.16205 0.31564 0.07164 0.26901 0.06105 58259.025736 0.000405 0.16592 0.04018 0.97857 0 2.06908 0.19240 1.76168 0.16381 0.34331 0.07677 0.29246 0.06540 58259.026457 0.000315 0.16399 0.03959 0.97248 0 2.70254 0.24604 2.30491 0.20984 0.44319 0.09910 0.37799 0.08452 58259.027128 0.000356 0.16829 0.04246 0.96748 0 2.25692 0.21334 1.92210 0.18169 0.37982 0.08885 0.32352 0.07567 58259.027962 0.000477 0.14016 0.03351 0.96970 0 2.09876 0.17753 1.78614 0.15109 0.29415 0.06577 0.25042 0.05599 58259.028835 0.000396 0.19553 0.04213 0.99270 0 2.34075 0.20570 1.99476 0.17530 0.45769 0.09004 0.39004 0.07673 58259.029594 0.000362 0.19437 0.04765 0.98400 0 1.96771 0.19784 1.67509 0.16842 0.38246 0.08552 0.32575 0.07284 58259.030427 0.000472 0.11458 0.02706 0.98160 0 2.57053 0.19573 2.18408 0.16630 0.29452 0.06586 0.25042 0.05599 58259.031338 0.000440 0.13715 0.03270 0.95395 0 2.36934 0.19607 2.01504 0.16675 0.32496 0.07266 0.27632 0.06179 58259.032556 0.000778 0.16002 0.02765 0.96654 0 2.20483 0.14298 1.87687 0.12171 0.35282 0.05650 0.30050 0.04812
