/* ** ** 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 55547.496941 0.000330 0.07087 0.01665 0.98246 0 11.35845 0.69754 4.91752 0.29702 0.80498 0.18252 0.35774 0.07999 55547.497587 0.000315 0.10183 0.02452 0.98165 0 9.27900 0.67898 3.63837 0.26409 0.94490 0.21674 0.36955 0.08387 55547.498246 0.000344 0.12451 0.02792 0.97479 0 10.28811 0.77598 3.15168 0.23770 1.28099 0.27051 0.39268 0.08295 55547.499259 0.000668 0.13343 0.02058 0.97403 0 10.21063 0.54142 3.28255 0.17396 1.36243 0.19734 0.43585 0.06313 55547.500292 0.000365 0.09047 0.02207 0.97619 0 10.95004 0.76542 3.46575 0.24218 0.99063 0.23151 0.31293 0.07321 55547.500992 0.000336 0.12902 0.03067 0.98276 0 8.67758 0.70038 2.73700 0.22087 1.11960 0.25036 0.35146 0.07859 55547.501684 0.000356 0.11063 0.02682 0.95935 0 9.71870 0.73286 2.99935 0.22616 1.07513 0.24769 0.33064 0.07619 55547.502465 0.000425 0.08992 0.02163 0.96599 0 9.88667 0.68056 3.06393 0.21091 0.88900 0.20490 0.27476 0.06331 55547.503290 0.000399 0.10576 0.02490 0.94928 0 9.33754 0.68774 2.88405 0.21239 0.98757 0.22083 0.30585 0.06839 55547.504146 0.000457 0.08730 0.02096 0.94937 0 9.58497 0.64740 2.98431 0.20151 0.83679 0.19282 0.26011 0.05993 55547.504919 0.000315 0.11952 0.02913 0.98165 0 9.92703 0.78907 3.05305 0.24270 1.18644 0.27333 0.36464 0.08402 55547.505561 0.000327 0.13082 0.03036 0.93805 0 9.80860 0.77449 3.02505 0.23886 1.28320 0.28003 0.39689 0.08661 55547.506279 0.000391 0.13116 0.02742 0.97037 0 9.88539 0.71652 3.03205 0.21977 1.29658 0.25428 0.39761 0.07798 55547.507017 0.000347 0.09969 0.02336 0.94167 0 11.60495 0.81352 3.55303 0.24908 1.15685 0.25868 0.35457 0.07928 55547.507919 0.000556 0.07735 0.01796 0.94792 0 9.26261 0.58018 2.84188 0.17801 0.71651 0.16022 0.22015 0.04923 55547.509424 0.000949 0.13530 0.01827 0.96341 0 9.59033 0.45121 2.94183 0.13840 1.29753 0.16425 0.39774 0.05035
