/* ** ** 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 55670.215742 0.000396 0.13695 0.01063 0.99270 0 23.08061 0.61387 21.12389 0.56179 3.16081 0.23050 2.89361 0.21099 55670.216534 0.000396 0.13832 0.01070 0.99270 0 22.93796 0.61495 20.92439 0.56095 3.17268 0.23035 2.89232 0.21005 55670.217330 0.000399 0.14622 0.01130 0.99275 0 21.93295 0.60111 19.84785 0.54390 3.20707 0.23173 2.90046 0.20954 55670.218094 0.000365 0.15719 0.01220 1.00000 0 22.29929 0.63685 19.95264 0.56983 3.50526 0.25286 3.13638 0.22625 55670.218855 0.000396 0.13545 0.01051 0.99270 0 23.76437 0.63125 21.35415 0.56723 3.21892 0.23476 2.89361 0.21099 55670.219651 0.000399 0.13720 0.01059 1.00000 0 23.32410 0.62065 20.87839 0.55557 3.20018 0.23180 2.86492 0.20751 55670.220435 0.000385 0.15101 0.01197 0.99248 0 21.66374 0.61248 19.48190 0.55073 3.27142 0.24231 2.93843 0.21774 55670.221202 0.000382 0.13822 0.01061 1.00000 0 24.09380 0.64523 21.76891 0.58296 3.33036 0.23965 3.00899 0.21650 55670.222035 0.000451 0.12197 0.00932 1.00000 0 22.78872 0.57402 20.79158 0.52370 2.77949 0.20049 2.53323 0.18274 55670.222900 0.000414 0.12985 0.01013 0.98601 0 23.55817 0.61116 21.27682 0.55199 3.05902 0.22514 2.76383 0.20343 55670.223658 0.000344 0.16379 0.01311 0.99160 0 22.11404 0.65196 20.07859 0.59198 3.62215 0.26951 3.28854 0.24465 55670.224396 0.000394 0.14449 0.01105 1.00000 0 22.40938 0.60880 20.34185 0.55256 3.23800 0.23148 2.93393 0.20970 55670.225146 0.000356 0.15530 0.01197 1.00000 0 22.80135 0.64637 20.77313 0.58886 3.54094 0.25375 3.22774 0.23129 55670.225828 0.000327 0.18256 0.01420 1.00000 0 21.11018 0.64830 19.33668 0.59378 3.85393 0.27544 3.53110 0.25239 55670.226561 0.000405 0.14559 0.01118 0.99286 0 21.65184 0.59093 19.72081 0.53820 3.15227 0.22624 2.87187 0.20610 55670.227405 0.000440 0.13154 0.01003 0.99342 0 22.07732 0.57482 20.00237 0.52078 2.90411 0.20809 2.62922 0.18840 55670.228505 0.000660 0.15165 0.00889 0.99561 0 22.08253 0.46671 20.04805 0.42369 3.34874 0.18317 3.04053 0.16628
