/* ** ** 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 58422.902421 0.000422 0.13681 0.01049 0.97260 0 22.86811 0.60422 20.45411 0.54037 3.12869 0.22516 2.79670 0.20128 58422.903208 0.000365 0.16724 0.01294 0.97619 0 21.44257 0.62470 19.29894 0.56225 3.58609 0.25702 3.22743 0.23131 58422.903945 0.000373 0.16099 0.01252 0.98450 0 21.62964 0.62214 19.43061 0.55889 3.48222 0.25165 3.12825 0.22607 58422.904683 0.000365 0.15032 0.01163 0.99206 0 23.40768 0.65229 21.02856 0.58599 3.51856 0.25389 3.16102 0.22809 58422.905427 0.000379 0.15544 0.01228 1.00000 0 21.40001 0.61306 19.12444 0.54789 3.32634 0.24495 2.97396 0.21901 58422.906173 0.000367 0.14964 0.01192 0.99213 0 22.89236 0.64720 20.57328 0.58163 3.42562 0.25503 3.07857 0.22919 58422.906914 0.000373 0.14742 0.01130 1.00000 0 23.34629 0.64521 20.97884 0.57978 3.44178 0.24604 3.09285 0.22110 58422.907707 0.000420 0.13106 0.01003 0.99310 0 23.41610 0.60909 21.04291 0.54736 3.06888 0.22087 2.75786 0.19848 58422.908497 0.000370 0.15073 0.01170 0.99219 0 22.97978 0.64071 20.64885 0.57572 3.46373 0.25097 3.11248 0.22552 58422.909220 0.000353 0.15367 0.01202 0.98361 0 23.74314 0.67089 21.33545 0.60286 3.64869 0.26617 3.27865 0.23917 58422.909981 0.000408 0.14070 0.01071 0.99291 0 22.52780 0.60784 20.24628 0.54628 3.16967 0.22565 2.84872 0.20280 58422.910794 0.000405 0.13924 0.01080 1.00000 0 22.45135 0.60911 20.17575 0.54737 3.12604 0.22710 2.80915 0.20408 58422.911561 0.000362 0.15874 0.01257 1.00000 0 21.95970 0.63792 19.61866 0.56993 3.48596 0.25668 3.11671 0.22952 58422.912273 0.000350 0.15335 0.01185 1.00000 0 23.81409 0.67105 21.40261 0.60309 3.65190 0.26283 3.28208 0.23621 58422.912991 0.000367 0.15679 0.01240 0.99213 0 22.05162 0.63603 19.71097 0.56855 3.45748 0.25460 3.09197 0.22770 58422.913954 0.000596 0.16232 0.00958 0.99515 0 22.93710 0.50630 20.61388 0.45502 3.72312 0.20379 3.34598 0.18315
