/* ** ** 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 58195.978830 0.000466 0.16138 0.03883 0.93168 0 1.97584 0.17533 1.65228 0.14662 0.31887 0.07130 0.26711 0.05973 58195.979643 0.000347 0.18574 0.04528 0.99167 0 2.14629 0.20847 1.81249 0.17605 0.39865 0.08914 0.33670 0.07529 58195.980294 0.000304 0.24482 0.06116 0.98095 0 1.89938 0.21158 1.59354 0.17750 0.46500 0.10398 0.38900 0.08698 58195.980936 0.000339 0.22061 0.05613 0.99145 0 1.80485 0.19418 1.52416 0.16398 0.39817 0.09181 0.33617 0.07751 58195.981781 0.000506 0.14253 0.03406 0.97714 0 1.96801 0.16600 1.64356 0.13861 0.28050 0.06273 0.23431 0.05239 58195.982594 0.000307 0.23966 0.05965 0.96226 0 1.94950 0.21298 1.64284 0.17947 0.46722 0.10448 0.39281 0.08784 58195.983378 0.000477 0.13921 0.03329 0.98788 0 2.09576 0.17763 1.76520 0.14961 0.29176 0.06524 0.24581 0.05496 58195.984232 0.000376 0.20275 0.05048 0.98462 0 1.80314 0.18424 1.52167 0.15547 0.36559 0.08301 0.30884 0.07012 58195.985172 0.000564 0.12749 0.03032 0.98462 0 1.95302 0.15822 1.63655 0.13257 0.24900 0.05568 0.20868 0.04666 58195.986214 0.000477 0.14855 0.03666 0.96364 0 1.95401 0.17190 1.65102 0.14525 0.29028 0.06693 0.24526 0.05655 58195.987444 0.000752 0.12631 0.02564 0.98462 0 2.04320 0.14041 1.71589 0.11791 0.25807 0.04930 0.21702 0.04146
