/* ** ** 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 58728.930170 0.000330 0.21520 0.05323 1.00000 0 1.90402 0.20137 1.63431 0.17284 0.40974 0.09162 0.35146 0.07859 58728.930937 0.000437 0.20493 0.04176 0.96689 0 2.30068 0.19291 1.93854 0.16255 0.47148 0.08756 0.39792 0.07389 58728.931782 0.000408 0.16732 0.04105 0.97163 0 2.05282 0.19089 1.72273 0.16020 0.34348 0.07798 0.28862 0.06551 58728.932488 0.000298 0.18727 0.04590 0.98058 0 2.50814 0.25149 2.11656 0.21221 0.46970 0.10504 0.39670 0.08870 58728.933101 0.000315 0.22526 0.05592 0.96330 0 2.00660 0.21627 1.68912 0.18208 0.45202 0.10108 0.38159 0.08533 58728.933755 0.000339 0.20984 0.05246 0.97436 0 1.96388 0.20561 1.64940 0.17269 0.41210 0.09355 0.34685 0.07872 58728.934557 0.000463 0.21020 0.04158 0.97500 0 2.25271 0.18660 1.89664 0.15712 0.47351 0.08505 0.39810 0.07150 58728.935373 0.000353 0.18262 0.04472 1.00000 0 2.13954 0.21344 1.79994 0.17957 0.39072 0.08737 0.32842 0.07344 58728.936093 0.000367 0.19913 0.04388 0.99213 0 2.35903 0.21806 1.99808 0.18468 0.46974 0.09395 0.39749 0.07950 58728.936903 0.000443 0.24965 0.05153 0.98693 0 1.87431 0.17386 1.57595 0.14618 0.46792 0.08628 0.39453 0.07275 58728.937850 0.000503 0.34235 0.05702 0.95977 0 2.03695 0.17043 1.72077 0.14396 0.69735 0.10042 0.59036 0.08500 58728.939299 0.000946 0.21225 0.02965 0.98471 0 2.15694 0.12743 1.83342 0.10832 0.45780 0.05795 0.39032 0.04941
