/* ** ** 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 57803.059883 0.000295 0.18258 0.01443 0.99020 0 23.22614 0.71015 21.30860 0.65147 4.24054 0.30894 3.89790 0.28401 57803.060462 0.000284 0.20702 0.01632 1.00000 0 21.27118 0.69849 19.56328 0.64245 4.40355 0.31551 4.05178 0.29026 57803.061024 0.000278 0.19213 0.01539 1.00000 0 22.89542 0.72846 21.14952 0.67291 4.39890 0.32346 4.06134 0.29866 57803.061602 0.000301 0.19010 0.01564 1.00000 0 21.19363 0.67709 19.47597 0.62223 4.02897 0.30549 3.70308 0.28090 57803.062221 0.000318 0.18375 0.01449 0.99091 0 21.23872 0.65425 19.64609 0.60519 3.90256 0.28324 3.60992 0.26200 57803.062797 0.000258 0.22232 0.01772 1.00000 0 21.59871 0.73265 19.97681 0.67763 4.80187 0.34624 4.44132 0.32024 57803.063318 0.000263 0.23871 0.01903 1.00000 0 19.87321 0.70227 18.37613 0.64937 4.74384 0.33896 4.38547 0.31336 57803.063879 0.000298 0.19279 0.01515 1.00000 0 21.89091 0.69204 20.01638 0.63273 4.22035 0.30358 3.85710 0.27740 57803.064447 0.000269 0.22625 0.01785 0.98925 0 20.71762 0.70509 19.16305 0.65219 4.68727 0.33360 4.33555 0.30857 57803.064999 0.000284 0.20771 0.01644 0.98980 0 21.32641 0.69733 19.59605 0.64072 4.42961 0.31940 4.07503 0.29383 57803.065581 0.000298 0.18478 0.01441 1.00000 0 22.60028 0.69645 20.84875 0.64246 4.17603 0.29918 3.85509 0.27617 57803.066177 0.000298 0.20129 0.01592 1.00000 0 20.67678 0.67238 19.06211 0.61986 4.16200 0.30009 3.83765 0.27672 57803.066808 0.000333 0.17903 0.01398 1.00000 0 20.86080 0.63440 19.29586 0.58681 3.73479 0.26860 3.45462 0.24845 57803.067456 0.000315 0.19013 0.01477 1.00000 0 21.02886 0.65727 19.44996 0.60792 3.99822 0.28424 3.69802 0.26290 57803.068081 0.000310 0.20019 0.01561 0.99065 0 20.32691 0.64783 18.79770 0.59909 4.06921 0.28961 3.76293 0.26781 57803.068697 0.000307 0.18086 0.01412 0.99057 0 22.89400 0.69511 20.92480 0.63527 4.14063 0.29780 3.78363 0.27212 57803.069264 0.000260 0.23812 0.01929 1.00000 0 19.85965 0.70309 18.37072 0.65038 4.72890 0.34456 4.37431 0.31872 57803.069817 0.000292 0.20090 0.01579 1.00000 0 21.27920 0.68758 19.55528 0.63188 4.27502 0.30630 3.93143 0.28163
