/* ** ** 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 59696.922121 0.000394 0.09252 0.01372 0.97794 0 9.01741 0.38737 8.20402 0.35240 0.83428 0.11837 0.76022 0.10786 59696.922870 0.000356 0.09920 0.01492 0.98374 0 9.08937 0.41482 8.26168 0.37711 0.90162 0.12926 0.81906 0.11740 59696.923620 0.000394 0.09260 0.01424 0.97059 0 8.71897 0.38506 7.93602 0.35044 0.80737 0.11891 0.73474 0.10821 59696.924337 0.000324 0.11528 0.01724 0.99107 0 8.66033 0.42055 7.82653 0.38002 0.99835 0.14120 0.90240 0.12762 59696.925124 0.000463 0.07490 0.01113 0.99375 0 9.22811 0.36274 8.33430 0.32760 0.69122 0.09909 0.62331 0.08934 59696.926345 0.000758 0.09301 0.01028 0.97597 0 8.51223 0.27317 7.65049 0.24550 0.79175 0.08376 0.71249 0.07538 59696.988035 0.000336 0.10954 0.01677 1.00000 0 8.45440 0.40715 7.71778 0.37168 0.92605 0.13456 0.84516 0.12280 59696.988793 0.000422 0.08799 0.01316 1.00000 0 8.50115 0.36196 7.69947 0.32782 0.74802 0.10726 0.67879 0.09730 59696.989583 0.000367 0.09847 0.01483 0.99213 0 8.82664 0.39538 8.06355 0.36120 0.86919 0.12498 0.79399 0.11417 59696.990315 0.000365 0.09498 0.01407 0.99206 0 9.23623 0.40747 8.43809 0.37226 0.87725 0.12406 0.80133 0.11333 59696.991036 0.000356 0.10193 0.01554 0.98374 0 8.70387 0.40158 7.94870 0.36674 0.88721 0.12892 0.81024 0.11773 59696.991742 0.000350 0.10871 0.01621 0.98347 0 8.47567 0.40071 7.74368 0.36611 0.92140 0.13031 0.84174 0.11904 59696.992506 0.000414 0.08901 0.01316 0.99301 0 8.67867 0.37274 7.92479 0.34037 0.77251 0.10925 0.70540 0.09976 59696.993307 0.000388 0.09299 0.01394 0.98507 0 8.83887 0.38817 8.07362 0.35456 0.82196 0.11782 0.75078 0.10762 59696.994114 0.000420 0.08856 0.01307 0.97931 0 8.72307 0.36816 7.96555 0.33618 0.77248 0.10925 0.70540 0.09976 59696.995162 0.000628 0.09547 0.01137 0.98618 0 8.78501 0.30859 8.02219 0.28180 0.83872 0.09545 0.76589 0.08716
