/* ** ** 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 56036.043405 0.000651 0.36099 0.03074 0.98667 0 5.82876 0.25412 4.87072 0.21232 2.10414 0.15388 1.76269 0.12886 56036.044647 0.000590 0.39196 0.03344 0.96569 0 6.09029 0.27304 5.08467 0.22795 2.38717 0.17325 1.99193 0.14458 56036.045882 0.000645 0.35393 0.02949 0.98655 0 6.11545 0.26015 5.09280 0.21665 2.16444 0.15506 1.80245 0.12912 56036.047138 0.000611 0.36203 0.03045 0.98578 0 6.30451 0.27245 5.25348 0.22702 2.28241 0.16469 1.90118 0.13718 56036.048429 0.000680 0.35998 0.03051 0.97447 0 5.69021 0.24664 4.74914 0.20585 2.04835 0.14916 1.70908 0.12445 56036.049826 0.000718 0.33998 0.02822 0.96774 0 5.82791 0.24137 4.85953 0.20126 1.98136 0.14250 1.65199 0.11881 56036.051235 0.000692 0.33449 0.02755 0.98326 0 6.12349 0.25323 5.08653 0.21035 2.04823 0.14588 1.70032 0.12110 56036.053035 0.001108 0.36353 0.02330 0.97911 0 5.96642 0.19732 4.96316 0.16413 2.16900 0.11909 1.80502 0.09910
