/* ** ** 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 58287.165049 0.000278 0.22477 0.01832 0.98958 0 20.08602 0.69061 18.24932 0.62747 4.51479 0.33359 4.10412 0.30326 58287.165595 0.000269 0.24495 0.01959 0.98925 0 19.45468 0.69330 17.80350 0.63446 4.76542 0.34111 4.36088 0.31215 58287.166145 0.000281 0.23326 0.01876 0.97938 0 19.61967 0.68128 17.93815 0.62289 4.57658 0.33193 4.18473 0.30351 58287.166704 0.000278 0.21787 0.01733 0.98958 0 21.00108 0.70384 19.10126 0.64014 4.57547 0.33009 4.15990 0.30008 58287.167233 0.000252 0.24266 0.01953 0.97701 0 21.23260 0.74564 19.21129 0.67460 5.15225 0.37316 4.65139 0.33689 58287.167734 0.000249 0.25418 0.02043 1.00000 0 20.26961 0.74586 18.26459 0.67213 5.15209 0.36816 4.63976 0.33162 58287.168252 0.000269 0.22200 0.01767 1.00000 0 21.26188 0.72482 19.25473 0.65638 4.72004 0.33957 4.27090 0.30729 58287.168790 0.000269 0.23153 0.01842 0.98925 0 20.68366 0.71422 18.63729 0.64350 4.78892 0.34321 4.31539 0.30923 58287.169322 0.000263 0.24310 0.01928 1.00000 0 19.89939 0.70354 18.11261 0.64037 4.83745 0.34347 4.40489 0.31276 58287.169863 0.000278 0.21911 0.01758 1.00000 0 20.55165 0.70205 18.67339 0.63792 4.50298 0.32696 4.09755 0.29756 58287.170422 0.000281 0.21221 0.01702 1.00000 0 21.17756 0.70820 19.11837 0.63939 4.49406 0.32756 4.05714 0.29581 58287.170986 0.000284 0.21014 0.01673 0.98980 0 21.46257 0.70464 19.51471 0.64068 4.51016 0.32712 4.09845 0.29725 58287.171527 0.000258 0.25235 0.02049 1.00000 0 19.37713 0.71063 17.61109 0.64588 4.88978 0.35416 4.44234 0.32175 58287.172045 0.000260 0.25148 0.02023 0.96667 0 20.32209 0.73128 18.13751 0.65262 5.11056 0.36772 4.56545 0.32848 58287.172575 0.000269 0.22835 0.01832 0.97849 0 20.85480 0.71881 19.02486 0.65572 4.76222 0.34496 4.34471 0.31468 58287.173104 0.000260 0.23346 0.01874 1.00000 0 20.55751 0.72439 18.80879 0.66277 4.79930 0.34620 4.39101 0.31675 58287.173651 0.000286 0.22785 0.01802 1.00000 0 19.55437 0.66963 17.78242 0.60893 4.45547 0.31762 4.05074 0.28878 58287.174192 0.000255 0.25223 0.02027 1.00000 0 20.03715 0.73024 18.06885 0.65849 5.05387 0.36191 4.55910 0.32634 58287.174707 0.000260 0.22073 0.01775 0.98889 0 21.91481 0.74246 20.03283 0.67870 4.83734 0.35269 4.42183 0.32240 58287.175234 0.000266 0.23422 0.01885 1.00000 0 20.29407 0.70733 18.46589 0.64352 4.75328 0.34487 4.32119 0.31341 58287.175757 0.000258 0.24224 0.01959 0.98876 0 20.30649 0.72335 18.44330 0.65696 4.91907 0.35723 4.47006 0.32461 58287.176420 0.000405 0.21522 0.01462 0.97857 0 20.07889 0.56654 18.37558 0.51848 4.32133 0.26697 3.95467 0.24432
