/* ** ** 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 58259.268466 0.000489 0.14898 0.01159 0.99408 0 17.31948 0.48126 15.68357 0.43579 2.58022 0.18752 2.33643 0.16980 58259.269381 0.000425 0.16212 0.01280 0.99320 0 18.18189 0.52920 16.47675 0.47952 2.94757 0.21630 2.66989 0.19583 58259.270301 0.000495 0.15457 0.01180 0.98246 0 16.90769 0.47285 15.37160 0.42986 2.61341 0.18564 2.37684 0.16883 58259.271224 0.000428 0.17730 0.01368 0.99324 0 16.80623 0.50587 15.31529 0.46100 2.97974 0.21166 2.71639 0.19295 58259.272127 0.000475 0.16060 0.01240 0.97561 0 16.92069 0.48032 15.45928 0.43884 2.71743 0.19518 2.48274 0.17832 58259.273027 0.000425 0.17958 0.01411 0.99320 0 16.46499 0.49927 15.04667 0.45626 2.95686 0.21432 2.70221 0.19586 58259.273869 0.000417 0.17469 0.01367 0.97917 0 17.50151 0.52316 15.99088 0.47800 3.05736 0.22117 2.79346 0.20208 58259.274711 0.000425 0.17387 0.01369 0.97959 0 17.25633 0.51685 15.70697 0.47043 3.00041 0.21847 2.73032 0.19881 58259.275550 0.000414 0.18467 0.01435 1.00000 0 16.82416 0.52402 15.16452 0.47222 3.10698 0.22114 2.79689 0.19907 58259.276409 0.000446 0.16085 0.01236 1.00000 0 17.82694 0.50940 16.16940 0.46203 2.86751 0.20452 2.60130 0.18552 58259.277312 0.000457 0.16590 0.01282 1.00000 0 16.84987 0.49265 15.21570 0.44481 2.79545 0.19989 2.52277 0.18038 58259.278168 0.000399 0.19148 0.01495 0.99275 0 16.92122 0.52956 15.17612 0.47494 3.24010 0.23170 2.90947 0.20802 58259.279005 0.000437 0.17563 0.01362 1.00000 0 16.86335 0.50718 15.03570 0.45217 2.96167 0.21178 2.63971 0.18874 58259.279985 0.000544 0.18704 0.01262 0.99468 0 16.68133 0.45129 15.00882 0.40600 3.12015 0.19278 2.80681 0.17341
