/* ** ** 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 56086.972941 0.000480 0.42279 0.03640 0.98193 0 8.94145 0.42077 5.70122 0.26751 3.78039 0.27259 2.42602 0.17440 56086.973977 0.000556 0.35787 0.03001 0.97396 0 9.48231 0.40820 5.89976 0.25359 3.39348 0.24420 2.11466 0.15202 56086.975056 0.000524 0.43944 0.03817 0.97790 0 8.40514 0.40068 5.03877 0.24018 3.69353 0.26815 2.21642 0.16093 56086.976089 0.000509 0.44474 0.03831 0.99432 0 8.36987 0.39955 5.11597 0.24421 3.72243 0.26691 2.27112 0.16285 56086.977041 0.000443 0.50510 0.04445 0.96732 0 8.55755 0.43693 5.31032 0.27105 4.32242 0.30978 2.67897 0.19195 56086.977952 0.000469 0.48262 0.04231 0.98148 0 8.38674 0.42056 5.15371 0.25840 4.04764 0.29108 2.48706 0.17879 56086.978974 0.000553 0.35263 0.02943 0.97382 0 9.68564 0.41248 6.06453 0.25826 3.41543 0.24511 2.14196 0.15370 56086.979929 0.000402 0.44027 0.03863 1.00000 0 10.22804 0.49605 6.36803 0.30879 4.50306 0.32923 2.80732 0.20521 56086.980803 0.000472 0.43626 0.03742 0.96933 0 9.40288 0.44255 5.76378 0.27126 4.10209 0.29410 2.51548 0.18037 56086.981755 0.000480 0.36946 0.03121 0.99398 0 10.54045 0.46336 6.46412 0.28415 3.89429 0.28095 2.39029 0.17240 56086.983129 0.000894 0.39172 0.02430 0.98382 0 10.13932 0.33229 6.25942 0.20509 3.97174 0.20921 2.45261 0.12915
