/* ** ** 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 56399.077766 0.000417 0.26881 0.04372 0.98611 0 4.26932 0.32503 2.57934 0.19418 1.14763 0.16494 0.70181 0.09982 56399.078782 0.000599 0.22291 0.03498 0.96618 0 4.12668 0.27861 2.26873 0.15315 0.91989 0.13029 0.50576 0.07162 56399.079882 0.000501 0.26506 0.04252 0.98844 0 3.95975 0.29343 2.19089 0.16233 1.04955 0.14931 0.58279 0.08289 56399.080880 0.000498 0.27184 0.04339 0.94186 0 4.04420 0.29935 2.27270 0.16822 1.09937 0.15548 0.61831 0.08744 56399.081895 0.000512 0.32234 0.05287 0.96045 0 3.25131 0.26090 1.80922 0.14519 1.04803 0.14993 0.58322 0.08344 56399.082876 0.000469 0.39878 0.06056 0.95338 0 3.57856 0.28876 1.97822 0.15963 1.42705 0.18359 0.78793 0.10136 56399.133179 0.000341 0.26713 0.04308 0.96610 0 4.04426 0.30078 3.23816 0.24079 1.08035 0.15458 0.86961 0.12442 56399.133914 0.000394 0.26366 0.04286 0.97059 0 3.54293 0.26202 2.81810 0.20842 0.93412 0.13524 0.74322 0.10760 56399.134736 0.000428 0.24820 0.03950 0.97297 0 3.51695 0.25114 2.78934 0.19918 0.87290 0.12417 0.69202 0.09844 56399.135511 0.000347 0.30278 0.04900 0.97500 0 3.56029 0.27999 2.82813 0.22241 1.07800 0.15245 0.85612 0.12107 56399.136183 0.000324 0.31841 0.05207 0.98214 0 3.58494 0.28930 2.84538 0.22961 1.14149 0.16237 0.90592 0.12886 56399.136834 0.000327 0.27758 0.04416 0.97345 0 4.20157 0.31099 3.32908 0.24640 1.16627 0.16425 0.92413 0.13014 56399.137655 0.000495 0.19926 0.02898 0.98830 0 4.31343 0.25708 3.42083 0.20388 0.85951 0.11400 0.68144 0.09038
