/* ** ** 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 58646.296521 0.000417 0.32247 0.01189 1.00000 0 47.94006 0.87090 42.80246 0.77751 15.45909 0.49586 13.80094 0.44263 58646.297369 0.000431 0.32062 0.01180 1.00000 0 46.17163 0.83846 41.67271 0.75674 14.80332 0.47368 13.36055 0.42748 58646.298231 0.000431 0.31346 0.01152 1.00000 0 46.94556 0.84401 42.54321 0.76486 14.71572 0.47164 13.33574 0.42742 58646.299099 0.000437 0.30417 0.01120 1.00000 0 47.42660 0.84305 42.98384 0.76407 14.42575 0.46531 13.07446 0.42172 58646.299962 0.000425 0.31808 0.01165 1.00000 0 47.20303 0.85152 42.77658 0.77167 15.01418 0.47850 13.60624 0.43363 58646.300836 0.000448 0.30478 0.01110 1.00000 0 46.64759 0.82569 42.27670 0.74833 14.21722 0.45239 12.88506 0.41000 58646.301715 0.000431 0.31298 0.01154 1.00000 0 46.85213 0.84190 42.46295 0.76303 14.66399 0.47226 13.29029 0.42802 58646.302569 0.000422 0.32753 0.01207 1.00000 0 46.12815 0.84655 41.80382 0.76719 15.10845 0.48275 13.69209 0.43749 58646.303440 0.000448 0.29461 0.01076 1.00000 0 47.91726 0.83456 43.42531 0.75633 14.11705 0.45292 12.79367 0.41046 58646.304299 0.000411 0.32704 0.01213 1.00000 0 46.99543 0.86368 42.59172 0.78275 15.36931 0.49489 13.92915 0.44852 58646.305127 0.000417 0.32355 0.01204 1.00000 0 46.68796 0.85716 42.31410 0.77685 15.10602 0.48911 13.69082 0.44329 58646.305995 0.000451 0.30325 0.01114 1.00000 0 46.22650 0.81875 41.89454 0.74202 14.01837 0.45092 12.70479 0.40867 58646.306883 0.000437 0.30782 0.01133 1.00000 0 47.11119 0.83969 42.69717 0.76102 14.50159 0.46687 13.14285 0.42312 58646.307815 0.000495 0.31841 0.01088 1.00000 0 46.73783 0.78633 42.35517 0.71259 14.88198 0.44276 13.48641 0.40124
