/* ** ** 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 56338.002759 0.000436 0.07454 0.02331 0.96559 1 9.44506 0.78120 2.02959 0.16786 0.70404 0.21228 0.15188 0.04579 56338.004087 0.000376 0.07208 0.01109 0.98462 0 11.41923 0.43976 10.46846 0.40315 0.82311 0.12264 0.75456 0.11243 56338.005345 0.000883 0.10047 0.00883 0.98689 0 10.64538 0.28087 9.75870 0.25748 1.06959 0.08963 0.98048 0.08216 56338.006534 0.000307 0.09082 0.01410 0.98113 0 11.15257 0.48854 10.22562 0.44794 1.01290 0.15092 0.92869 0.13837 56338.007165 0.000324 0.08546 0.01310 0.99107 0 11.34328 0.47629 10.38717 0.43615 0.96940 0.14294 0.88817 0.13089 56338.008210 0.000720 0.09383 0.00931 0.99197 0 11.26501 0.32208 10.25061 0.29309 1.05695 0.10045 0.96135 0.09140 56338.009341 0.000411 0.10266 0.01313 0.99296 0 10.43098 0.40756 9.56433 0.37370 1.07085 0.13039 0.98186 0.11955 56338.010047 0.000295 0.10039 0.01567 0.99020 0 10.38753 0.48392 9.52612 0.44379 1.04275 0.15537 0.95627 0.14248 56338.010635 0.000292 0.09756 0.01485 1.00000 0 10.88880 0.49841 9.98410 0.45700 1.06226 0.15418 0.97401 0.14137 56338.012049 0.001123 0.10271 0.00808 0.98196 0 10.55649 0.24849 9.66475 0.22750 1.08425 0.08136 0.99241 0.07447
