/* ** ** 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 55938.040843 0.000443 0.40539 0.03456 0.99346 0 7.70689 0.35278 6.41213 0.29346 3.12432 0.22469 2.60183 0.18702 55938.041714 0.000428 0.37514 0.03124 0.98649 0 8.75553 0.37955 7.35017 0.31856 3.28451 0.23353 2.75703 0.19602 55938.042588 0.000446 0.35601 0.02997 0.97403 0 8.86409 0.38045 7.38548 0.31698 3.15574 0.22852 2.62912 0.19036 55938.043468 0.000434 0.37094 0.03152 0.97333 0 8.74052 0.38222 7.22483 0.31593 3.24224 0.23620 2.68032 0.19522 55938.044345 0.000443 0.39178 0.03313 0.98693 0 8.11740 0.36331 6.75062 0.30215 3.18027 0.22818 2.63872 0.18931 55938.045299 0.000512 0.36111 0.03031 0.97175 0 7.60058 0.32640 6.34737 0.27256 2.74468 0.19790 2.29326 0.16538 55938.046225 0.000414 0.39191 0.03295 0.97902 0 8.73172 0.38761 7.24948 0.32176 3.42202 0.24438 2.83967 0.20277 55938.047079 0.000440 0.37014 0.03087 0.98684 0 8.69041 0.37761 7.18056 0.31200 3.21664 0.22896 2.65728 0.18913 55938.047979 0.000460 0.36047 0.03038 0.99371 0 8.30266 0.36159 6.94402 0.30242 2.99284 0.21598 2.50257 0.18060 55938.048804 0.000365 0.44155 0.03783 0.98413 0 8.80714 0.41674 7.25778 0.34342 3.88878 0.27771 3.20608 0.22894 55938.049628 0.000460 0.33987 0.02785 0.98113 0 9.10547 0.37709 7.55934 0.31304 3.09468 0.21884 2.56838 0.18161 55938.050534 0.000446 0.38106 0.03221 0.97403 0 8.33238 0.36724 6.89703 0.30398 3.17518 0.22897 2.62960 0.18964 55938.051402 0.000422 0.38772 0.03302 0.98630 0 8.48383 0.37942 7.09033 0.31704 3.28937 0.23841 2.74537 0.19891 55938.052256 0.000431 0.36330 0.03050 1.00000 0 8.80669 0.38186 7.30703 0.31678 3.19948 0.22999 2.65422 0.19078 55938.053109 0.000422 0.40197 0.03404 0.99315 0 8.31915 0.38028 6.86779 0.31389 3.34402 0.23835 2.76222 0.19688 55938.053974 0.000443 0.35347 0.02923 0.98693 0 9.10544 0.38677 7.48618 0.31799 3.21848 0.22832 2.64655 0.18775 55938.054868 0.000451 0.35595 0.03012 1.00000 0 8.48062 0.36877 7.05948 0.30697 3.01866 0.21915 2.51516 0.18258 55938.055786 0.000466 0.35360 0.02920 1.00000 0 8.51801 0.36111 7.08409 0.30030 3.01200 0.21349 2.50661 0.17764
