/* ** ** 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 59254.212042 0.000590 0.19543 0.01572 0.98529 0 11.25678 0.36456 9.92270 0.32134 2.19994 0.16203 1.93835 0.14273 59254.213214 0.000582 0.21497 0.01710 0.98507 0 10.49886 0.35181 9.28223 0.31097 2.25691 0.16283 1.99564 0.14399 59254.214493 0.000697 0.17258 0.01338 0.96680 0 11.10215 0.32880 9.87215 0.29237 1.91599 0.13732 1.70378 0.12211 59254.215766 0.000576 0.20820 0.01720 0.98995 0 10.53634 0.35410 9.36830 0.31485 2.19364 0.16553 1.95045 0.14718 59254.216909 0.000567 0.20736 0.01676 0.98469 0 11.01010 0.36705 9.72751 0.32428 2.28302 0.16810 2.01869 0.14865 59254.218116 0.000639 0.18341 0.01436 1.00000 0 11.02773 0.34068 9.79156 0.30250 2.02264 0.14556 1.79702 0.12933 59254.219395 0.000639 0.19304 0.01514 0.99548 0 10.53875 0.33530 9.35046 0.29752 2.03443 0.14580 1.80446 0.12932 59254.220627 0.000593 0.19304 0.01536 0.99024 0 11.31659 0.35999 10.03995 0.31938 2.18457 0.15933 1.93820 0.14138 59254.222062 0.000842 0.15396 0.01161 0.97938 0 10.96849 0.29867 9.70331 0.26422 1.68866 0.11870 1.49357 0.10499
