/* ** ** 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 56008.154939 0.000388 0.17370 0.01382 0.99254 0 19.67567 0.59239 16.86800 0.50755 3.41765 0.25161 2.93039 0.21564 56008.155674 0.000347 0.20049 0.01576 1.00000 0 18.83900 0.60858 16.48278 0.53234 3.77701 0.27070 3.30854 0.23707 56008.156408 0.000388 0.18017 0.01420 0.98507 0 19.09159 0.58537 16.55255 0.50754 3.43971 0.24976 2.98018 0.21640 56008.157169 0.000373 0.19835 0.01574 0.97674 0 18.07982 0.57847 15.73788 0.50353 3.58613 0.26037 3.12209 0.22670 56008.157936 0.000394 0.17074 0.01342 1.00000 0 19.65940 0.59146 16.94677 0.50979 3.35656 0.24373 2.89252 0.21003 56008.158715 0.000385 0.17926 0.01387 0.98496 0 19.72454 0.59898 16.99666 0.51609 3.53580 0.25172 3.04463 0.21672 56008.159487 0.000388 0.17670 0.01398 0.98507 0 19.44332 0.58665 16.77709 0.50621 3.43561 0.25126 2.96638 0.21684 56008.160263 0.000388 0.17686 0.01389 1.00000 0 19.32199 0.58426 16.78121 0.50744 3.41726 0.24776 2.96696 0.21516 56008.161047 0.000391 0.18024 0.01420 0.98519 0 18.99637 0.57887 16.40580 0.49995 3.42385 0.24868 2.95777 0.21477 56008.161877 0.000440 0.15191 0.01173 0.98684 0 20.06045 0.55977 17.42699 0.48621 3.04736 0.21932 2.64805 0.19051 56008.162754 0.000431 0.15393 0.01196 0.97987 0 20.39297 0.57288 17.60348 0.49449 3.13914 0.22733 2.70813 0.19613 56008.163582 0.000396 0.16985 0.01366 0.99270 0 19.46540 0.58458 16.70967 0.50178 3.30622 0.24658 2.83897 0.21173 56008.164406 0.000428 0.16392 0.01266 0.97973 0 19.39011 0.55951 16.66970 0.48101 3.17851 0.22778 2.73810 0.19619 56008.165268 0.000434 0.15727 0.01230 0.96667 0 19.96578 0.56302 17.25511 0.48652 3.14011 0.22903 2.71425 0.19788 56008.166168 0.000466 0.16379 0.01202 1.00000 0 19.49243 0.53787 16.78365 0.46314 3.19269 0.21712 2.75332 0.18726
