/* ** ** 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 57580.948862 0.000422 0.18535 0.02884 0.98630 0 4.25504 0.26005 3.71372 0.22697 0.78867 0.11287 0.68834 0.09851 57580.949641 0.000356 0.20820 0.03294 0.98374 0 4.48422 0.29410 3.91374 0.25669 0.93363 0.13441 0.81486 0.11731 57580.950390 0.000394 0.22375 0.03516 0.96324 0 3.89502 0.26010 3.39950 0.22701 0.87151 0.12398 0.76064 0.10821 57580.951246 0.000463 0.18260 0.02807 0.96875 0 4.05504 0.24428 3.53916 0.21320 0.74043 0.10471 0.64624 0.09139 57580.952155 0.000446 0.21211 0.03302 0.96104 0 3.65590 0.23782 3.19079 0.20757 0.77545 0.10967 0.67680 0.09571 57580.953043 0.000443 0.22220 0.03218 0.97424 0 4.13691 0.25378 3.61062 0.22150 0.91923 0.12060 0.80229 0.10526 57580.996619 0.000466 0.18430 0.02856 0.96273 0 4.75738 0.29248 3.48808 0.21444 0.87681 0.12473 0.64287 0.09145 57580.997525 0.000440 0.22191 0.03528 0.96053 0 4.15082 0.28004 3.04335 0.20532 0.92111 0.13260 0.67535 0.09722 57580.998610 0.000645 0.19583 0.02739 0.95894 0 4.20158 0.23931 3.08057 0.17546 0.82280 0.10511 0.60327 0.07707
