/* ** ** 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 57801.137430 0.000726 0.17425 0.01377 0.98406 0 16.48203 0.49851 9.07146 0.27437 2.87204 0.20976 1.58073 0.11545 57801.138914 0.000758 0.16744 0.01307 0.98855 0 16.48618 0.48463 9.07374 0.26673 2.76050 0.19965 1.51934 0.10988 57801.141023 0.001351 0.18288 0.01037 0.98205 0 16.44093 0.36432 9.04884 0.20051 3.00665 0.15697 1.65481 0.08639 57801.184764 0.000437 0.16813 0.01338 0.98675 0 16.59566 0.49539 15.51732 0.46320 2.79021 0.20592 2.60891 0.19254 57801.185655 0.000454 0.17710 0.01364 0.98089 0 15.81334 0.47111 14.78583 0.44050 2.80058 0.19893 2.61860 0.18600 57801.186812 0.000703 0.18725 0.01097 0.99514 0 17.00244 0.39555 15.89767 0.36985 3.18378 0.17124 2.97690 0.16011 57801.318172 0.000503 0.16757 0.01327 0.99425 0 15.07315 0.45285 13.57516 0.40784 2.52585 0.18505 2.27483 0.16666 57801.319150 0.000475 0.19166 0.01490 0.99390 0 14.32187 0.44954 12.89855 0.40486 2.74499 0.19525 2.47219 0.17585 57801.320226 0.000602 0.18267 0.01295 1.00000 0 14.36965 0.40074 12.94157 0.36091 2.62484 0.17115 2.36398 0.15414
