/* ** ** 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 55159.389275 0.000576 0.21451 0.03377 0.96482 0 2.78859 0.18256 2.40574 0.15750 0.59819 0.08565 0.51603 0.07389 55159.390172 0.000321 0.15125 0.03513 1.00000 0 3.00081 0.25479 2.59327 0.22018 0.45388 0.09814 0.39215 0.08479 55159.391025 0.000532 0.21313 0.03324 0.98370 0 3.00787 0.19777 2.59732 0.17077 0.64107 0.09066 0.55341 0.07826 55159.392174 0.000616 0.22290 0.03506 0.97183 0 2.49627 0.16721 2.15867 0.14459 0.55643 0.07918 0.48127 0.06848 55159.393115 0.000324 0.14548 0.03488 0.98214 0 2.89424 0.25045 2.50256 0.21656 0.42106 0.09415 0.36424 0.08145 55159.393994 0.000556 0.21892 0.03406 0.96875 0 2.89414 0.19107 2.49136 0.16446 0.63360 0.08926 0.54637 0.07697 55159.395120 0.000570 0.20914 0.03274 0.97462 0 2.87203 0.18724 2.48093 0.16175 0.60065 0.08547 0.51887 0.07383 55159.396289 0.000599 0.20752 0.03245 0.97585 0 2.75091 0.17828 2.37663 0.15402 0.57088 0.08124 0.49318 0.07018 55159.397409 0.000521 0.17204 0.03118 0.98228 0 2.80562 0.19572 2.40380 0.16769 0.48269 0.08074 0.41307 0.06906 55159.456785 0.000535 0.22729 0.03592 0.95676 0 2.89623 0.19503 2.46665 0.16610 0.65829 0.09412 0.56043 0.08013 55159.457850 0.000530 0.22145 0.03518 0.97268 0 2.94719 0.19903 2.49894 0.16875 0.65266 0.09385 0.55455 0.07972 55159.458955 0.000576 0.22577 0.03556 0.97487 0 2.66083 0.18012 2.27497 0.15400 0.60073 0.08542 0.51382 0.07306 55159.459832 0.000301 0.18421 0.04542 0.97115 0 2.49233 0.24165 2.12776 0.20630 0.45911 0.10407 0.39189 0.08884 55159.460680 0.000547 0.23066 0.03680 0.98942 0 2.68769 0.18560 2.29079 0.15817 0.61995 0.08915 0.52786 0.07589 55159.461750 0.000524 0.28838 0.04615 0.95028 0 2.38705 0.17838 2.04065 0.15249 0.68837 0.09743 0.58837 0.08327 55159.462595 0.000321 0.16465 0.03977 0.92785 0 2.80170 0.25601 2.36423 0.21604 0.46131 0.10316 0.38903 0.08699 55159.463321 0.000399 0.19568 0.04239 0.94928 0 2.35669 0.20620 2.01201 0.17604 0.46117 0.09140 0.39390 0.07807 55159.464496 0.000775 0.24907 0.03407 0.95820 0 2.47827 0.15197 2.11167 0.12948 0.61725 0.07546 0.52670 0.06439
