/* ** ** 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 57729.238787 0.000475 0.08729 0.01301 0.96951 0 7.94864 0.33238 7.14426 0.29876 0.69384 0.09923 0.62422 0.08928 57729.239577 0.000315 0.12273 0.01841 0.99083 0 8.39466 0.41954 7.55863 0.37774 1.03031 0.14571 0.92747 0.13116 57729.240326 0.000434 0.08517 0.01296 0.96667 0 8.76754 0.36499 7.88261 0.32814 0.74670 0.10928 0.67185 0.09831 57729.241061 0.000301 0.12708 0.01950 0.98077 0 8.39917 0.42998 7.58652 0.38837 1.06733 0.15440 0.96406 0.13946 57729.241767 0.000405 0.09797 0.01467 0.97143 0 8.33190 0.36910 7.45864 0.33039 0.81630 0.11674 0.72978 0.10438 57729.242557 0.000385 0.09062 0.01368 0.98496 0 9.17075 0.39422 8.28347 0.35608 0.83105 0.12022 0.75064 0.10859 57729.243301 0.000359 0.11739 0.01756 0.98387 0 7.74341 0.37656 6.99420 0.34012 0.90899 0.12855 0.82104 0.11611 57729.243972 0.000312 0.12321 0.01848 0.99074 0 8.41163 0.41996 7.59768 0.37932 1.03643 0.14657 0.93614 0.13239 57729.244661 0.000376 0.10756 0.01636 0.99231 0 7.84599 0.36942 7.08686 0.33368 0.84394 0.12208 0.76228 0.11027 57729.245480 0.000443 0.08458 0.01302 0.99346 0 8.31017 0.35066 7.50608 0.31673 0.70289 0.10404 0.63488 0.09397 57729.246293 0.000370 0.10186 0.01513 0.99219 0 8.57042 0.38918 7.74335 0.35162 0.87294 0.12345 0.78872 0.11154 57729.246967 0.000304 0.12575 0.01909 0.99048 0 8.40196 0.42722 7.58898 0.38588 1.05657 0.15112 0.95433 0.13649 57729.247583 0.000312 0.12776 0.01920 0.98148 0 8.27762 0.41698 7.47678 0.37664 1.05754 0.14973 0.95523 0.13525 57729.248217 0.000321 0.11487 0.01715 0.98198 0 8.85666 0.42450 7.99980 0.38343 1.01739 0.14388 0.91896 0.12996 57729.249114 0.000576 0.12550 0.01382 0.98995 0 8.58623 0.31174 7.75546 0.28158 1.07760 0.11205 0.97333 0.10121 57729.250442 0.000752 0.12676 0.01214 0.98846 0 8.55699 0.27174 7.73112 0.24552 1.08465 0.09801 0.97995 0.08855 57729.251634 0.000440 0.12471 0.01583 0.98684 0 8.62098 0.35805 7.78740 0.32343 1.07512 0.12894 0.97113 0.11647
