/* ** ** 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 59228.125055 0.000344 0.08329 0.01939 0.98319 0 4.77392 0.30984 4.12764 0.26789 0.39760 0.08891 0.34245 0.07657 59228.125958 0.000558 0.13210 0.02001 0.97927 0 4.60244 0.23912 3.99679 0.20765 0.60797 0.08652 0.52715 0.07500 59228.127173 0.000657 0.12216 0.01875 0.98238 0 4.14568 0.20939 3.59756 0.18170 0.50643 0.07339 0.43959 0.06370 59228.128434 0.000605 0.11089 0.01657 0.99043 0 5.07965 0.24042 4.41448 0.20894 0.56328 0.07982 0.48841 0.06921 59228.129650 0.000611 0.11879 0.01786 0.95735 0 4.78814 0.23275 4.14983 0.20172 0.56879 0.08093 0.49323 0.07018 59228.130761 0.000501 0.09309 0.01724 0.98569 0 4.64537 0.25602 4.02838 0.22200 0.43242 0.07644 0.37594 0.06646 59228.171878 0.000318 0.09884 0.02385 0.95455 0 4.45425 0.31846 3.75936 0.26879 0.44026 0.10146 0.37155 0.08562 59228.172812 0.000616 0.11628 0.01768 0.94836 0 4.98112 0.24332 4.19925 0.20511 0.57920 0.08340 0.48805 0.07027 59228.173848 0.000420 0.09354 0.01819 0.96344 0 5.26535 0.30316 4.44590 0.25598 0.49252 0.09146 0.41587 0.07722
