/* ** ** 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 58652.008946 0.000373 0.15612 0.01197 1.00000 0 21.42835 0.60318 19.83676 0.55838 3.34543 0.23856 3.09703 0.22085 58652.009652 0.000333 0.18319 0.01421 0.99130 0 20.75379 0.63327 19.14311 0.58411 3.80195 0.27114 3.50453 0.24991 58652.010352 0.000367 0.17005 0.01324 0.97638 0 20.42683 0.60072 18.90619 0.55600 3.47367 0.25051 3.21606 0.23194 58652.011040 0.000321 0.19275 0.01496 1.00000 0 20.48756 0.64240 18.97396 0.59494 3.94898 0.28029 3.65723 0.25958 58652.011660 0.000298 0.20250 0.01614 1.00000 0 20.33292 0.66526 18.83194 0.61615 4.11735 0.29928 3.81342 0.27719 58652.012342 0.000385 0.15923 0.01235 0.98496 0 20.51714 0.58600 19.00199 0.54272 3.26692 0.23554 3.02567 0.21814 58652.013057 0.000330 0.18972 0.01473 0.99123 0 20.22133 0.62874 18.72861 0.58233 3.83649 0.27289 3.55327 0.25274 58652.013752 0.000365 0.15966 0.01267 0.99206 0 21.12625 0.61088 19.56586 0.56576 3.37296 0.24932 3.12384 0.23091 58652.014498 0.000382 0.15636 0.01208 0.99242 0 20.87043 0.59159 19.32957 0.54791 3.26335 0.23459 3.02241 0.21727 58652.015268 0.000388 0.16240 0.01268 0.99254 0 19.84342 0.57656 18.29634 0.53162 3.22251 0.23360 2.96831 0.21519 58652.016029 0.000373 0.17006 0.01332 0.99225 0 19.58140 0.57976 18.13592 0.53696 3.33007 0.24142 3.08426 0.22360 58652.016755 0.000353 0.16617 0.01304 1.00000 0 20.91937 0.61883 19.37533 0.57315 3.47611 0.25267 3.21952 0.23402 58652.017487 0.000379 0.16619 0.01292 0.99237 0 19.86990 0.58821 18.31429 0.54215 3.30221 0.23737 3.04566 0.21894 58652.018219 0.000353 0.16478 0.01272 0.98361 0 21.81220 0.63618 20.09888 0.58614 3.59412 0.25694 3.31261 0.23683 58652.018914 0.000341 0.17648 0.01370 1.00000 0 20.61037 0.62425 19.08871 0.57816 3.63730 0.26004 3.36875 0.24084 58652.019628 0.000373 0.16708 0.01292 1.00000 0 20.03625 0.58773 18.55617 0.54432 3.34762 0.23942 3.10033 0.22173 58652.020375 0.000373 0.16354 0.01270 0.97674 0 20.77280 0.59894 19.23582 0.55463 3.39708 0.24492 3.14573 0.22680 58652.021136 0.000388 0.17318 0.01259 0.99254 0 21.28404 0.59963 19.71192 0.55534 3.68605 0.24712 3.41378 0.22886
