/* ** ** 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 55330.888985 0.000304 0.19448 0.01539 1.00000 0 21.11450 0.67055 19.28272 0.61230 4.10627 0.29761 3.75010 0.27182 55330.889639 0.000350 0.17265 0.01330 0.97521 0 21.29786 0.62617 19.68166 0.57865 3.67706 0.26190 3.40017 0.24218 55330.890284 0.000295 0.19879 0.01544 0.98039 0 21.77622 0.68613 20.16880 0.63548 4.32899 0.30722 4.00944 0.28455 55330.890906 0.000327 0.17272 0.01340 0.99115 0 22.29374 0.66111 20.65080 0.61239 3.85067 0.27595 3.56691 0.25562 55330.891540 0.000307 0.18563 0.01452 1.00000 0 21.80900 0.67327 20.20180 0.62365 4.04831 0.29087 3.74991 0.26943 55330.892142 0.000295 0.18687 0.01461 0.98039 0 22.96615 0.70654 21.27068 0.65438 4.29174 0.30836 3.97490 0.28559 55330.892709 0.000272 0.20335 0.01597 1.00000 0 22.43332 0.72527 20.78063 0.67184 4.56176 0.32658 4.22568 0.30252 55330.893282 0.000301 0.19193 0.01527 1.00000 0 21.32261 0.67537 19.75439 0.62570 4.09246 0.29875 3.79148 0.27678 55330.893947 0.000365 0.15432 0.01227 0.98413 0 21.82687 0.61846 20.21575 0.57281 3.36842 0.25033 3.11979 0.23185 55330.894673 0.000362 0.16400 0.01268 0.99200 0 21.20737 0.61377 19.64454 0.56854 3.47804 0.24925 3.22172 0.23088 55330.895339 0.000304 0.18504 0.01458 0.99048 0 22.09216 0.68243 20.46181 0.63207 4.08785 0.29630 3.78616 0.27443 55330.895949 0.000307 0.19079 0.01469 1.00000 0 21.72044 0.67490 20.12221 0.62524 4.14412 0.29191 3.83919 0.27043 55330.896624 0.000367 0.15585 0.01217 0.99213 0 21.66510 0.61563 20.06629 0.57020 3.37642 0.24561 3.12728 0.22749 55330.897332 0.000341 0.16830 0.01307 1.00000 0 21.60996 0.63811 20.01509 0.59101 3.63699 0.26131 3.36856 0.24203 55330.898122 0.000448 0.20466 0.01315 1.00000 0 20.58975 0.54187 19.06985 0.50187 4.21391 0.24697 3.90284 0.22873
