/* ** ** 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 57137.044373 0.000301 0.15514 0.01189 1.00000 0 28.08479 0.78990 24.87876 0.69960 4.35717 0.31056 3.85628 0.27488 57137.044940 0.000266 0.18352 0.01416 1.00000 0 27.01883 0.83384 23.74588 0.73275 4.95839 0.35063 4.35507 0.30795 57137.045502 0.000295 0.15511 0.01210 0.99020 0 28.23126 0.80516 25.11351 0.71625 4.37907 0.31791 3.89531 0.28279 57137.046103 0.000307 0.14973 0.01172 1.00000 0 27.90508 0.78558 24.68550 0.69489 4.17821 0.30527 3.69449 0.26999 57137.046824 0.000414 0.17255 0.01062 0.98983 0 29.41073 0.69268 26.04370 0.61334 5.07488 0.28869 4.49341 0.25558 57137.062773 0.000321 0.13201 0.00995 1.00000 0 29.98326 0.77724 27.49499 0.71271 3.95819 0.27998 3.63184 0.25688 57137.063371 0.000278 0.16376 0.01267 1.00000 0 27.32782 0.79576 25.32021 0.73730 4.47514 0.32072 4.14639 0.29716 57137.063968 0.000318 0.14152 0.01089 1.00000 0 27.65614 0.74599 25.62937 0.69132 3.91396 0.28203 3.62711 0.26136 57137.064604 0.000318 0.13859 0.01069 0.97273 0 28.74014 0.75989 26.63597 0.70425 3.98298 0.28850 3.69136 0.26738 57137.065180 0.000258 0.18328 0.01406 1.00000 0 26.76926 0.81694 24.80904 0.75712 4.90617 0.34520 4.54689 0.31992 57137.065721 0.000284 0.15743 0.01220 1.00000 0 27.91265 0.79462 25.70986 0.73186 4.39432 0.31661 4.04607 0.29151 57137.066277 0.000272 0.16976 0.01333 1.00000 0 26.91219 0.80332 24.61035 0.73457 4.56857 0.33172 4.18056 0.30361 57137.066861 0.000312 0.14162 0.01098 0.99074 0 28.27972 0.76839 25.96027 0.70532 4.00484 0.29080 3.67264 0.26672 57137.067431 0.000258 0.16773 0.01307 1.00000 0 28.94538 0.85465 26.60584 0.78546 4.85495 0.34995 4.45522 0.32099 57137.067995 0.000307 0.14178 0.01091 1.00000 0 28.65022 0.77380 26.38839 0.71269 4.06195 0.29268 3.74070 0.26951 57137.068588 0.000286 0.15275 0.01184 0.98990 0 28.70327 0.80703 26.35349 0.74090 4.38452 0.31670 4.02562 0.29080 57137.069159 0.000284 0.16377 0.01220 0.98980 0 29.01186 0.81090 26.63445 0.74440 4.75140 0.32798 4.36255 0.30113
