/* ** ** 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 56443.004165 0.000454 0.21967 0.03452 0.96178 0 3.49020 0.23283 3.00246 0.20028 0.76669 0.10908 0.65985 0.09388 56443.004972 0.000353 0.25026 0.04042 0.96721 0 3.85511 0.27518 3.32034 0.23701 0.96478 0.13977 0.83095 0.12038 56443.005733 0.000408 0.22400 0.03568 0.97163 0 3.72769 0.25398 3.21187 0.21884 0.83501 0.12024 0.71957 0.10362 56443.006578 0.000437 0.20969 0.03292 0.98675 0 3.70232 0.24579 3.18922 0.21172 0.77633 0.11045 0.66871 0.09514 56443.007405 0.000391 0.21402 0.03374 0.97778 0 4.07296 0.26924 3.50815 0.23191 0.87171 0.12477 0.75083 0.10747 56443.008236 0.000440 0.22523 0.03493 0.98684 0 3.50861 0.23378 3.02343 0.20145 0.79025 0.11066 0.68113 0.09538 56443.008994 0.000318 0.26153 0.04119 0.93636 0 4.38133 0.30870 3.77326 0.26586 1.14584 0.16139 0.98681 0.13899 56443.009645 0.000333 0.23733 0.03835 0.96522 0 4.29559 0.29956 3.70160 0.25814 1.01947 0.14860 0.87859 0.12806 56443.010551 0.000573 0.22254 0.03098 0.98307 0 3.44543 0.20573 2.96972 0.17732 0.76673 0.09643 0.66084 0.08311 56443.071636 0.000362 0.26762 0.04342 0.98400 0 3.52087 0.26114 3.02342 0.22425 0.94224 0.13597 0.80880 0.11672 56443.072441 0.000437 0.20815 0.03271 0.98013 0 3.75952 0.24361 3.21673 0.20844 0.78254 0.11203 0.66954 0.09585 56443.073358 0.000480 0.20775 0.03270 0.97590 0 3.44956 0.22561 2.94046 0.19232 0.71666 0.10260 0.61168 0.08757 56443.074750 0.000906 0.19163 0.02208 0.96486 0 3.68631 0.16923 3.14839 0.14453 0.70642 0.07464 0.60317 0.06373
