/* ** ** 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 58910.035774 0.000284 0.17784 0.01379 0.97959 0 25.90628 0.77133 23.39022 0.69635 4.60712 0.32975 4.16089 0.29784 58910.036382 0.000324 0.14664 0.01143 0.99107 0 26.46056 0.72936 24.04386 0.66273 3.88015 0.28283 3.52718 0.25713 58910.036984 0.000278 0.17355 0.01352 1.00000 0 26.16242 0.78165 23.73926 0.70923 4.54061 0.32672 4.11915 0.29637 58910.037609 0.000347 0.13816 0.01052 1.00000 0 26.62737 0.70961 24.02749 0.64031 3.67887 0.26241 3.31711 0.23660 58910.038260 0.000304 0.15705 0.01199 0.99048 0 27.35421 0.76925 24.62788 0.69253 4.29598 0.30491 3.86596 0.27435 58910.038859 0.000295 0.15506 0.01193 1.00000 0 27.77389 0.78244 25.22660 0.71066 4.30657 0.30833 3.91613 0.28032 58910.039458 0.000304 0.16241 0.01280 0.98095 0 25.72021 0.74833 23.32211 0.67857 4.17730 0.30585 3.78845 0.27739 58910.040048 0.000286 0.16217 0.01251 1.00000 0 27.84478 0.80241 24.88163 0.71697 4.51561 0.32323 4.03480 0.28881 58910.040632 0.000298 0.16664 0.01295 0.99029 0 25.77986 0.75673 23.21415 0.68136 4.29594 0.30911 3.87685 0.27894 58910.041223 0.000292 0.16992 0.01316 0.99010 0 25.56068 0.75218 23.34837 0.68708 4.34336 0.31115 3.96746 0.28422 58910.041845 0.000330 0.14760 0.01134 0.98246 0 26.71881 0.73400 24.01752 0.65976 3.94365 0.28304 3.54859 0.25466 58910.042481 0.000307 0.15622 0.01194 1.00000 0 26.72652 0.75554 24.11959 0.68183 4.17514 0.29652 3.76755 0.26756 58910.043046 0.000258 0.18019 0.01409 1.00000 0 27.00088 0.82530 24.65856 0.75370 4.86529 0.35006 4.44313 0.31968 58910.043627 0.000324 0.14967 0.01145 0.97321 0 27.46691 0.75153 24.43542 0.66857 4.11085 0.29375 3.65825 0.26140 58910.044246 0.000295 0.16476 0.01290 1.00000 0 25.78577 0.75811 23.39138 0.68766 4.24845 0.30832 3.85122 0.27953 58910.044840 0.000298 0.17990 0.01362 0.97087 0 26.49646 0.76269 24.05785 0.69252 4.76661 0.33377 4.33062 0.30323
