/* ** ** 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 58565.960649 0.000142 0.29815 0.02461 1.00000 0 32.34110 1.28137 27.08090 1.07267 9.64242 0.69833 8.06924 0.58437 58565.960947 0.000156 0.27235 0.02181 1.00000 0 32.38108 1.21495 27.67602 1.03841 8.81900 0.62394 7.53786 0.53331 58565.961254 0.000150 0.25124 0.02007 0.96154 0 37.75097 1.34649 31.74671 1.13217 9.48445 0.67798 7.98062 0.57037 58565.961549 0.000145 0.25711 0.02055 1.00000 0 37.04673 1.35275 31.35496 1.14494 9.52510 0.67737 8.06076 0.57318 58565.961862 0.000168 0.23257 0.01858 1.00000 0 35.71094 1.25604 29.58739 1.04052 8.30514 0.59586 6.88302 0.49391 58565.962183 0.000153 0.25596 0.02047 1.00000 0 36.27533 1.32034 29.86131 1.08687 9.28511 0.66124 7.64576 0.54445 58565.962498 0.000162 0.23702 0.01913 1.00000 0 36.41279 1.31169 29.93950 1.07851 8.63041 0.62337 7.09636 0.51258 58565.962796 0.000136 0.29926 0.02469 1.00000 0 34.17028 1.36856 28.09868 1.12536 10.22585 0.73761 8.40870 0.60651 58565.963100 0.000168 0.23937 0.01918 1.00000 0 34.93851 1.23992 28.90992 1.02589 8.36332 0.60088 6.92074 0.49730 58565.963413 0.000145 0.26330 0.02161 0.98000 0 37.00058 1.38009 30.34789 1.13194 9.74231 0.71211 7.99123 0.58412 58565.963699 0.000142 0.27632 0.02272 1.00000 0 35.60524 1.36008 29.38266 1.12228 9.83841 0.71630 8.11764 0.59098 58565.963985 0.000145 0.27879 0.02281 0.98000 0 34.59969 1.31572 28.89815 1.09888 9.64620 0.69887 8.06924 0.58437 58565.964269 0.000139 0.29472 0.02441 1.00000 0 33.35620 1.32862 27.79920 1.10718 9.83088 0.71397 8.19561 0.59508 58565.964553 0.000145 0.27346 0.02214 1.00000 0 35.16683 1.33641 29.19937 1.10971 9.61665 0.68739 7.98062 0.57037 58565.964975 0.000278 0.24016 0.01510 0.98204 0 36.13867 0.98403 29.67466 0.80802 8.67915 0.49194 7.12671 0.40395
