/* ** ** 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 55934.411763 0.000347 0.10894 0.01661 0.96667 0 8.59854 0.40285 7.76932 0.36399 0.93671 0.13593 0.84593 0.12275 55934.412405 0.000295 0.11887 0.01782 1.00000 0 9.05231 0.45113 8.26142 0.41172 1.07603 0.15217 0.98203 0.13888 55934.413131 0.000431 0.08081 0.01203 0.97987 0 9.20726 0.37361 8.40370 0.34101 0.74408 0.10659 0.67909 0.09728 55934.413912 0.000350 0.11523 0.01601 0.98347 0 9.36213 0.41750 8.54577 0.38110 1.07880 0.14198 0.98468 0.12959 55934.415426 0.001163 0.12211 0.00925 0.97512 0 9.09445 0.22544 8.28718 0.20542 1.11049 0.07954 1.01171 0.07246 55934.416962 0.000373 0.09335 0.01401 0.99225 0 9.17920 0.39925 8.37988 0.36448 0.85687 0.12305 0.78227 0.11234 55934.417729 0.000394 0.09304 0.01410 0.97794 0 8.68184 0.38087 7.92928 0.34786 0.80778 0.11721 0.73780 0.10706 55934.418507 0.000385 0.09563 0.01450 0.95489 0 8.84686 0.38866 8.07905 0.35493 0.84604 0.12277 0.77266 0.11212 55934.419196 0.000304 0.11267 0.01763 0.96190 0 9.25109 0.44451 8.44555 0.40581 1.04228 0.15524 0.95137 0.14170 55934.420032 0.000532 0.11690 0.01325 0.96196 0 9.28087 0.33560 8.47195 0.30635 1.08493 0.11650 0.99025 0.10633 55934.420895 0.000330 0.12668 0.01865 0.97368 0 8.11357 0.40125 7.40866 0.36639 1.02783 0.14253 0.93850 0.13015 55934.421528 0.000304 0.11845 0.01794 0.98095 0 9.00487 0.44282 8.11944 0.39922 1.06664 0.15283 0.96259 0.13789 55934.422171 0.000339 0.10471 0.01560 0.98291 0 9.20208 0.42151 8.39990 0.38477 0.96353 0.13663 0.87957 0.12472 55934.423056 0.000547 0.11687 0.01295 0.97884 0 9.33883 0.33414 8.43824 0.30189 1.09139 0.11441 0.98542 0.10330
