/* ** ** 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 59750.177375 0.000440 0.11732 0.00880 0.99342 0 24.63943 0.59882 22.63434 0.55008 2.89059 0.20503 2.65604 0.18840 59750.178260 0.000446 0.11673 0.00871 0.99351 0 24.46616 0.59412 22.54136 0.54737 2.85588 0.20144 2.63183 0.18564 59750.179117 0.000411 0.12443 0.00958 0.98592 0 24.42776 0.61666 22.53911 0.56899 3.03944 0.22109 2.80444 0.20399 59750.179976 0.000448 0.11705 0.00878 0.99355 0 24.11310 0.58847 22.24913 0.54298 2.82248 0.20020 2.60429 0.18473 59750.180919 0.000495 0.10303 0.00776 0.99415 0 24.61680 0.56575 22.71414 0.52203 2.53630 0.18194 2.34026 0.16787 59750.181886 0.000472 0.11422 0.00866 0.98160 0 23.47608 0.56394 21.66024 0.52032 2.68140 0.19284 2.47400 0.17793 59750.182809 0.000446 0.11577 0.00895 0.99351 0 23.95050 0.58579 22.09835 0.54049 2.77264 0.20344 2.55822 0.18771 59750.183680 0.000425 0.12222 0.00919 1.00000 0 24.33858 0.60508 22.45600 0.55828 2.97471 0.21112 2.74462 0.19479 59750.184571 0.000466 0.11385 0.00859 0.98758 0 23.79624 0.57364 21.95565 0.52927 2.70923 0.19374 2.49968 0.17876 59750.185529 0.000492 0.12224 0.00859 0.98941 0 24.20356 0.56446 22.33152 0.52080 2.95867 0.19605 2.72983 0.18088
