/* ** ** 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 54182.422038 0.000556 0.14084 0.01085 0.97917 0 16.43838 0.43867 14.89075 0.39734 2.31518 0.16737 2.09602 0.15152 54182.423138 0.000544 0.13426 0.01022 0.99468 0 17.67525 0.46263 15.89246 0.41596 2.37305 0.16963 2.13209 0.15238 54182.424234 0.000553 0.13355 0.01022 0.97906 0 17.51057 0.45545 15.81361 0.41131 2.33848 0.16834 2.11431 0.15216 54182.425317 0.000530 0.15468 0.01185 0.98361 0 15.98460 0.44618 14.29583 0.39902 2.47257 0.17641 2.21123 0.15774 54182.426396 0.000550 0.13504 0.01048 0.98947 0 17.07071 0.45055 15.42370 0.40707 2.30531 0.16815 2.08195 0.15184 54182.427501 0.000556 0.13496 0.01055 0.98438 0 16.83982 0.44558 15.25210 0.40357 2.27278 0.16722 2.05693 0.15137 54182.428604 0.000547 0.13285 0.01025 0.97884 0 17.63031 0.45834 15.97461 0.41529 2.34222 0.17008 2.12286 0.15414 54182.429651 0.000501 0.14897 0.01151 0.97110 0 17.44557 0.47665 15.74407 0.43013 2.59882 0.18787 2.34555 0.16956 54182.430687 0.000535 0.14020 0.01073 0.98378 0 17.13664 0.45535 15.57392 0.41383 2.40256 0.17246 2.18340 0.15673 54182.431801 0.000579 0.13014 0.00990 0.97500 0 17.30831 0.44177 15.62837 0.39888 2.25250 0.16140 2.03435 0.14576 54182.433207 0.000828 0.13843 0.00873 0.98527 0 16.69417 0.36355 15.07164 0.32818 2.31098 0.13684 2.08815 0.12365 54182.483489 0.000602 0.12277 0.00939 0.98558 0 17.23645 0.42961 15.87745 0.39573 2.11615 0.15308 1.94899 0.14099 54182.484626 0.000535 0.13274 0.01042 1.00000 0 17.08842 0.45123 15.87675 0.41923 2.26835 0.16762 2.10745 0.15573 54182.485662 0.000501 0.14961 0.01170 0.98844 0 16.54092 0.46032 15.31887 0.42631 2.47463 0.18090 2.28965 0.16740 54182.486649 0.000486 0.14950 0.01146 0.99405 0 17.29452 0.47438 16.06899 0.44076 2.58558 0.18508 2.40236 0.17196 54182.487630 0.000495 0.14964 0.01160 0.97661 0 17.09993 0.47221 15.83422 0.43726 2.55886 0.18535 2.36743 0.17148 54182.488617 0.000492 0.13975 0.01082 0.99412 0 17.92573 0.48177 16.65558 0.44764 2.50507 0.18192 2.32756 0.16903 54182.489612 0.000503 0.14788 0.01148 0.97701 0 16.91347 0.46409 15.65878 0.42965 2.50123 0.18166 2.31387 0.16804 54182.490628 0.000512 0.13955 0.01066 0.97740 0 17.75368 0.47031 16.43607 0.43540 2.47759 0.17753 2.29487 0.16445 54182.491678 0.000538 0.12849 0.01015 0.98925 0 17.68855 0.45903 16.32059 0.42355 2.27277 0.16959 2.09808 0.15652 54182.492720 0.000503 0.14829 0.01143 0.99425 0 16.70013 0.46123 15.46192 0.42699 2.47644 0.17818 2.29588 0.16519 54182.494181 0.000958 0.13160 0.00761 1.00000 0 17.27494 0.33918 16.02893 0.31471 2.27334 0.12358 2.10941 0.11467
