/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 57367.488061 0.000561 0.12283 0.00943 0.97938 0 18.16350 0.45310 16.85765 0.42050 2.23100 0.16196 2.07073 0.15032 57367.489219 0.000596 0.11396 0.00884 0.98544 0 18.29455 0.44717 16.83625 0.41144 2.08492 0.15344 1.92032 0.14126 57367.490431 0.000616 0.10990 0.00830 0.99061 0 18.81907 0.45016 17.11079 0.40928 2.06821 0.14818 1.88177 0.13482 57367.491562 0.000515 0.13299 0.01034 0.99438 0 18.14408 0.47865 16.62499 0.43857 2.41303 0.17641 2.21261 0.16168 57367.492656 0.000579 0.11991 0.00910 1.00000 0 17.88359 0.44761 16.55865 0.41441 2.14435 0.15366 1.98527 0.14223 57367.493686 0.000451 0.15304 0.01205 0.98077 0 18.01934 0.50719 16.64022 0.46837 2.75766 0.20283 2.54788 0.18742 57367.494708 0.000570 0.11916 0.00907 0.98985 0 18.57965 0.46143 17.06762 0.42385 2.21387 0.15933 2.03718 0.14653 57367.495833 0.000556 0.12223 0.00934 0.98438 0 18.73307 0.46766 17.20202 0.42941 2.28980 0.16540 2.10289 0.15186 57367.496933 0.000544 0.12296 0.00957 0.99468 0 18.22208 0.46178 16.95304 0.42962 2.24065 0.16482 2.08463 0.15334 57367.498035 0.000558 0.13343 0.00990 0.99482 0 18.27521 0.45940 16.94958 0.42605 2.43838 0.17022 2.26091 0.15779
