/* ** ** 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 57517.915607 0.000359 0.19874 0.01571 0.99194 0 18.25626 0.59015 16.16076 0.52242 3.62827 0.26174 3.21291 0.23177 57517.916356 0.000385 0.17111 0.01377 0.99248 0 19.05085 0.57416 17.09264 0.51514 3.25979 0.24317 2.92468 0.21817 57517.917123 0.000382 0.18845 0.01456 1.00000 0 17.96557 0.55995 16.10678 0.50202 3.38569 0.23940 3.03536 0.21463 57517.917869 0.000365 0.19943 0.01557 0.98413 0 18.15043 0.57780 16.22423 0.51646 3.61980 0.25805 3.23404 0.23056 57517.918564 0.000330 0.20505 0.01606 0.99123 0 19.54357 0.63498 17.31207 0.56234 4.00750 0.28567 3.54886 0.25301 57517.919267 0.000373 0.19588 0.01558 0.98450 0 17.72683 0.56461 15.82833 0.50412 3.47242 0.25314 3.09874 0.22594 57517.919976 0.000336 0.21487 0.01700 1.00000 0 17.77059 0.59655 15.92939 0.53475 3.81828 0.27360 3.42254 0.24525 57517.920650 0.000339 0.20204 0.01608 1.00000 0 18.74554 0.61057 16.62976 0.54166 3.78732 0.27510 3.36207 0.24415 57517.921373 0.000385 0.17902 0.01393 0.98496 0 18.88143 0.57278 16.92975 0.51358 3.38007 0.24221 3.03065 0.21717 57517.922129 0.000370 0.20123 0.01586 0.97656 0 17.60937 0.56715 15.78920 0.50853 3.54359 0.25496 3.17753 0.22862 57517.922852 0.000353 0.19050 0.01522 0.99180 0 19.05669 0.59922 17.00013 0.53457 3.63024 0.26656 3.23730 0.23762 57517.923593 0.000388 0.17949 0.01404 0.99254 0 18.75704 0.57133 16.74620 0.51005 3.36670 0.24254 3.00280 0.21636 57517.924371 0.000391 0.17494 0.01360 0.99259 0 19.09076 0.57084 17.02926 0.50918 3.33983 0.23966 2.97907 0.21379 57517.925083 0.000321 0.22307 0.01767 0.98198 0 18.41064 0.62216 16.31919 0.55149 4.10689 0.29425 3.64234 0.26100 57517.925708 0.000304 0.22909 0.01796 0.99048 0 18.85071 0.64589 16.89967 0.57904 4.31847 0.30460 3.87183 0.27310 57517.926362 0.000350 0.20521 0.01655 1.00000 0 17.50603 0.57778 15.69529 0.51801 3.59238 0.26440 3.22074 0.23704 57517.927224 0.000512 0.17175 0.01199 0.99435 0 18.11248 0.48649 16.18441 0.43470 3.11078 0.20049 2.77936 0.17913
