/* ** ** 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 55685.946833 0.000298 0.11107 0.02745 1.00000 0 3.96197 0.30634 3.34836 0.25886 0.44007 0.10331 0.37267 0.08749 55685.947429 0.000298 0.11794 0.02877 0.98058 0 3.84059 0.30098 3.26487 0.25586 0.45297 0.10463 0.38560 0.08905 55685.948210 0.000483 0.07171 0.01661 0.98204 0 3.96682 0.23979 3.40693 0.20594 0.28446 0.06361 0.24431 0.05463 55685.949145 0.000451 0.07944 0.01845 0.96795 0 3.88863 0.24403 3.34013 0.20961 0.30892 0.06908 0.26534 0.05933 55685.950213 0.000616 0.14989 0.02266 0.98592 0 3.75518 0.20554 3.22788 0.17668 0.56285 0.07931 0.48386 0.06818 55685.951231 0.000402 0.09260 0.02167 0.97842 0 3.69977 0.25490 3.17866 0.21899 0.34261 0.07661 0.29461 0.06588 55685.951949 0.000315 0.13763 0.03300 0.97248 0 3.26245 0.26992 2.80697 0.23224 0.44902 0.10104 0.38631 0.08693 55685.952745 0.000480 0.06843 0.01583 0.99398 0 4.13038 0.24427 3.54900 0.20988 0.28264 0.06320 0.24283 0.05430 55685.953902 0.000677 0.05532 0.01270 0.95726 0 3.75878 0.19705 3.23267 0.16946 0.20792 0.04649 0.17887 0.04000 55685.954877 0.000298 0.10021 0.02464 0.99029 0 4.37146 0.31909 3.75532 0.27411 0.43806 0.10284 0.37633 0.08835 55685.955783 0.000608 0.11823 0.01974 0.95714 0 3.92244 0.21040 3.37140 0.18084 0.46374 0.07332 0.39867 0.06304 55685.956836 0.000446 0.08790 0.02050 0.98052 0 3.51498 0.23352 3.01873 0.20055 0.30896 0.06908 0.26534 0.05933 55685.957802 0.000521 0.06352 0.01487 0.97222 0 4.13246 0.23418 3.55246 0.20131 0.26249 0.05964 0.22575 0.05130
