/* ** ** 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 59342.250599 0.000457 0.24777 0.03949 0.94937 0 8.55024 0.60897 2.69923 0.19217 2.11850 0.30205 0.67078 0.09556 59342.251484 0.000428 0.26266 0.04205 0.97297 0 8.22176 0.60264 2.63455 0.19296 2.15953 0.30732 0.69201 0.09844 59342.252439 0.000527 0.19319 0.03051 0.96703 0 9.27003 0.59645 2.93210 0.18863 1.79090 0.25826 0.56581 0.08155 59342.253330 0.000365 0.26612 0.04295 0.97619 0 9.60264 0.71544 3.01518 0.22451 2.55547 0.36582 0.80595 0.11532 59342.254120 0.000425 0.25731 0.04110 0.97279 0 8.72873 0.63410 2.71772 0.19734 2.24603 0.31952 0.69685 0.09913 59342.254893 0.000347 0.46964 0.07583 0.97500 0 6.64487 0.61782 2.09573 0.19478 3.12071 0.41193 0.98868 0.13048 59342.255648 0.000408 0.26898 0.04253 0.97872 0 8.90225 0.65359 2.75302 0.20213 2.39450 0.33532 0.74036 0.10367 59342.256542 0.000486 0.20762 0.03276 0.98214 0 9.35444 0.62287 2.89670 0.19284 1.94213 0.27786 0.60080 0.08597 59342.257552 0.000524 0.23102 0.03664 0.94475 0 8.11158 0.55562 2.51693 0.17237 1.87390 0.26810 0.57972 0.08295 59342.258640 0.000564 0.22053 0.03526 0.92821 0 7.99619 0.54201 2.45849 0.16664 1.76341 0.25534 0.54197 0.07847 59342.259745 0.000541 0.21620 0.03405 0.95187 0 8.35266 0.56484 2.58860 0.17512 1.80584 0.25684 0.55983 0.07964 59342.261024 0.000738 0.19412 0.02851 0.95294 0 7.71058 0.45820 2.36817 0.14072 1.49675 0.20106 0.45954 0.06173
