/* ** ** 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 59016.001455 0.000515 0.27435 0.00991 1.00000 0 44.21711 0.74044 40.79720 0.68317 12.13105 0.38813 11.19248 0.35810 59016.002465 0.000495 0.28371 0.01024 1.00000 0 45.03482 0.76623 41.15722 0.70023 12.77693 0.40693 11.67655 0.37185 59016.003423 0.000463 0.29218 0.01066 1.00000 0 45.95035 0.79717 42.42696 0.73605 13.42591 0.43104 12.39649 0.39799 59016.004375 0.000489 0.28544 0.01036 1.00000 0 44.96947 0.76992 41.38922 0.70855 12.83609 0.41084 11.80745 0.37791 59016.005356 0.000492 0.27560 0.01002 1.00000 0 45.94851 0.77431 42.27545 0.71240 12.66360 0.40797 11.64599 0.37513 59016.006351 0.000503 0.28265 0.01032 1.00000 0 43.60120 0.74652 40.11784 0.68686 12.32368 0.39742 11.34029 0.36569 59016.007335 0.000480 0.28176 0.01026 1.00000 0 46.04576 0.78518 42.35562 0.72225 12.97382 0.41732 11.93149 0.38379 59016.008313 0.000498 0.28183 0.01024 1.00000 0 44.28806 0.75499 40.89289 0.69711 12.48150 0.40037 11.52467 0.36968 59016.009612 0.000802 0.28539 0.00816 0.99639 0 44.06219 0.59355 40.68259 0.54802 12.57482 0.31699 11.61033 0.29267
