/* ** ** 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 55623.312424 0.000396 0.09628 0.01426 0.94161 0 9.00457 0.38403 8.12928 0.34668 0.86699 0.12293 0.78411 0.11119 55623.313188 0.000367 0.10602 0.01579 1.00000 0 8.25690 0.38483 7.43954 0.34674 0.87541 0.12381 0.78872 0.11154 55623.314062 0.000506 0.07598 0.01128 0.98286 0 8.52998 0.33511 7.59156 0.29821 0.64809 0.09283 0.57644 0.08257 55623.314927 0.000359 0.09899 0.01487 1.00000 0 9.03850 0.40821 8.06133 0.36403 0.89472 0.12819 0.79957 0.11454 55623.315708 0.000422 0.07955 0.01229 0.99315 0 9.28110 0.37864 8.34444 0.34040 0.73829 0.10998 0.66268 0.09870 55623.316510 0.000379 0.10905 0.01626 0.96947 0 8.15911 0.37781 7.30310 0.33818 0.88972 0.12615 0.79646 0.11294 55623.317418 0.000530 0.09852 0.01461 0.70491 0 8.78604 0.39114 7.88119 0.35085 0.86564 0.12243 0.77649 0.10981 55623.318443 0.000495 0.07708 0.01134 0.98246 0 8.79708 0.34546 7.82848 0.30740 0.67804 0.09616 0.60209 0.08537 55623.319250 0.000312 0.12245 0.01839 0.98148 0 8.73291 0.43216 7.80444 0.38619 1.06936 0.15166 0.95425 0.13531 55623.319872 0.000310 0.13477 0.02029 0.97196 0 8.05885 0.41635 7.15258 0.36953 1.08609 0.15360 0.96314 0.13621 55623.320529 0.000347 0.11665 0.01764 0.98333 0 8.15131 0.39615 7.20438 0.35013 0.95081 0.13620 0.84023 0.12036 55623.321186 0.000310 0.12610 0.01875 0.99065 0 8.65159 0.43305 7.64363 0.38260 1.09098 0.15277 0.96387 0.13497 55623.321837 0.000341 0.10314 0.01571 0.99153 0 9.20312 0.42502 8.13198 0.37555 0.94917 0.13773 0.83870 0.12170 55623.322563 0.000385 0.09126 0.01397 0.94737 0 9.55837 0.40716 8.44493 0.35973 0.87232 0.12824 0.77070 0.11330 55623.323281 0.000333 0.12410 0.01883 0.97391 0 8.07360 0.40374 7.13343 0.35673 1.00192 0.14352 0.88524 0.12681 55623.324183 0.000570 0.13140 0.01448 0.98985 0 8.38210 0.31411 7.44918 0.27911 1.10143 0.11410 0.98085 0.10159 55623.325118 0.000365 0.09896 0.01484 0.96825 0 9.29401 0.41395 8.21211 0.36576 0.91973 0.13175 0.81268 0.11641 55623.325922 0.000440 0.11501 0.01615 0.90132 0 8.29590 0.35898 7.48819 0.32394 0.95411 0.12744 0.86223 0.11517
