/* ** ** 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 57747.185128 0.000408 0.18157 0.01430 1.00000 0 17.27202 0.53260 15.43617 0.47596 3.13601 0.22728 2.80307 0.20315 57747.185984 0.000448 0.17650 0.01365 0.98710 0 16.48374 0.49756 14.77242 0.44590 2.90937 0.20713 2.60658 0.18557 57747.186881 0.000448 0.17366 0.01341 0.99355 0 16.60455 0.49691 14.91082 0.44622 2.88362 0.20529 2.58965 0.18437 57747.187749 0.000420 0.18056 0.01442 0.97931 0 16.98915 0.52473 15.19327 0.46928 3.06748 0.22596 2.74305 0.20208 57747.188886 0.000718 0.17250 0.01045 0.98913 0 17.47666 0.40235 15.64496 0.36019 3.01470 0.16893 2.69913 0.15126 57747.299527 0.000472 0.15349 0.01174 0.98160 0 17.70651 0.49254 16.26833 0.45252 2.71780 0.19366 2.49796 0.17801 57747.300433 0.000434 0.17305 0.01331 0.98000 0 17.02964 0.50161 15.70435 0.46258 2.94702 0.20946 2.71543 0.19300 57747.301283 0.000417 0.17470 0.01359 0.99306 0 17.18331 0.51497 15.85200 0.47504 3.00192 0.21557 2.77044 0.19895 57747.302244 0.000544 0.16133 0.01173 0.99337 0 16.65340 0.44742 15.31115 0.41134 2.68661 0.18156 2.47016 0.16688 57747.366842 0.000457 0.14891 0.01145 1.00000 0 18.73218 0.51981 16.86698 0.46802 2.78943 0.20000 2.51217 0.18009 57747.367736 0.000437 0.15861 0.01228 0.99338 0 18.38235 0.52482 16.69251 0.47658 2.91566 0.20992 2.64704 0.19058 57747.368809 0.000637 0.16836 0.01078 0.99091 0 17.54042 0.42629 15.95266 0.38770 2.95309 0.17486 2.68578 0.15903
