/* ** ** 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 58823.194808 0.000347 0.13807 0.01043 0.98333 0 29.19941 0.77381 24.61835 0.65234 4.03163 0.28510 3.39548 0.24010 58823.195532 0.000376 0.12486 0.00960 0.98462 0 28.88696 0.73335 24.61534 0.62489 3.60672 0.26180 3.07401 0.22312 58823.196220 0.000312 0.14586 0.01125 0.97222 0 30.46058 0.83037 25.81955 0.70382 4.44309 0.32044 3.76449 0.27145 58823.196874 0.000341 0.12795 0.00999 0.99153 0 30.63955 0.79345 26.18638 0.67813 3.92037 0.28865 3.35116 0.24673 58823.197540 0.000324 0.13789 0.01057 0.99107 0 30.34659 0.80542 25.95538 0.68887 4.18448 0.30095 3.57906 0.25741 58823.198139 0.000275 0.16572 0.01290 0.98947 0 29.90324 0.87636 25.41975 0.74492 4.95555 0.35732 4.20502 0.30321 58823.198714 0.000301 0.15579 0.01193 0.99038 0 29.23519 0.82713 24.85184 0.70308 4.55464 0.32417 3.87251 0.27562 58823.199328 0.000312 0.13929 0.01079 0.99074 0 31.05478 0.84242 26.40231 0.71612 4.32559 0.31392 3.67732 0.26690 58823.200060 0.000420 0.10967 0.00828 0.98621 0 29.66049 0.70815 25.31871 0.60448 3.25288 0.23303 2.77671 0.19892 58823.200809 0.000330 0.13737 0.01054 0.99123 0 30.04000 0.79978 25.60096 0.68160 4.12655 0.29679 3.51571 0.25285 58823.201475 0.000336 0.12588 0.00979 1.00000 0 31.48252 0.81393 26.84055 0.69392 3.96290 0.29065 3.37828 0.24777 58823.202106 0.000295 0.14905 0.01139 1.00000 0 30.78195 0.85609 26.23856 0.72973 4.58817 0.32655 3.91048 0.27832 58823.202696 0.000295 0.15364 0.01198 1.00000 0 29.67274 0.84624 25.06833 0.71491 4.55882 0.33094 3.85758 0.27999 58823.203581 0.000590 0.14710 0.00817 1.00000 0 30.15887 0.59725 25.69079 0.50877 4.43632 0.23012 3.77902 0.19602
