/* ** ** 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 58141.431974 0.000318 0.29325 0.01066 1.00000 0 66.18715 1.14607 61.74643 1.06918 19.40962 0.62060 18.10727 0.57896 58141.432613 0.000321 0.28046 0.01014 1.00000 0 69.17799 1.17531 64.14846 1.08980 19.40180 0.61945 17.99828 0.57460 58141.433256 0.000321 0.27920 0.01017 1.00000 0 68.98827 1.17946 64.00761 1.09430 19.26122 0.61939 17.86608 0.57451 58141.433886 0.000310 0.29338 0.01068 1.00000 0 68.28262 1.18761 63.69031 1.10774 20.03310 0.64078 18.68578 0.59768 58141.434497 0.000301 0.30300 0.01109 1.00000 0 67.85667 1.20007 63.25871 1.11874 20.56067 0.65866 19.16701 0.61402 58141.435122 0.000324 0.28774 0.01055 1.00000 0 66.13638 1.14800 61.38327 1.06548 19.03027 0.61484 17.66497 0.57069 58141.435770 0.000324 0.28019 0.01014 1.00000 0 68.63026 1.16511 63.66079 1.08073 19.22955 0.61470 17.83565 0.57009 58141.436424 0.000330 0.27687 0.00999 1.00000 0 67.79922 1.14519 63.23935 1.06817 18.77146 0.59886 17.50897 0.55858 58141.437049 0.000295 0.30044 0.01096 1.00000 0 70.22010 1.23581 65.08872 1.14550 21.09721 0.67386 19.56672 0.62499 58141.437659 0.000315 0.28872 0.01048 1.00000 0 68.28046 1.17661 63.32456 1.09120 19.71361 0.63004 18.29177 0.58456 58141.438299 0.000324 0.28633 0.01044 1.00000 0 66.92344 1.14979 62.14671 1.06766 19.16225 0.61612 17.79212 0.57203 58141.438927 0.000304 0.30601 0.01126 1.00000 0 66.23473 1.18028 61.72584 1.09992 20.26866 0.65255 18.88493 0.60800 58141.439532 0.000301 0.30598 0.01112 1.00000 0 67.66713 1.19935 63.11624 1.11869 20.70473 0.65694 19.31228 0.61276 58141.440145 0.000312 0.30059 0.01099 1.00000 0 65.77198 1.16165 61.34777 1.08351 19.77046 0.63291 18.44058 0.59033 58141.440773 0.000315 0.29282 0.01074 1.00000 0 66.65491 1.16288 62.17496 1.08472 19.51811 0.62958 18.20630 0.58726 58141.441395 0.000307 0.29574 0.01072 1.00000 0 68.61337 1.19497 63.99781 1.11459 20.29197 0.64495 18.92695 0.60157 58141.442037 0.000336 0.27997 0.01009 1.00000 0 66.37049 1.12256 61.81610 1.04555 18.58145 0.59171 17.30884 0.55118 58141.442694 0.000321 0.28116 0.01020 1.00000 0 68.89199 1.16951 63.66614 1.08075 19.36959 0.62104 17.88804 0.57353 58141.443380 0.000365 0.28525 0.00980 1.00000 0 66.34069 1.07667 61.87848 1.00425 18.92338 0.57271 17.65055 0.53419
