/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 56981.885575 0.000552 0.41498 0.11016 0.97368 1 1.54900 0.22140 0.52126 0.07448 0.64281 0.14378 0.21622 0.04835 56981.886606 0.000479 0.46915 0.12542 0.96970 1 1.57911 0.24083 0.55484 0.08461 0.74084 0.16266 0.26100 0.05730 56981.887565 0.000479 0.39606 0.10511 1.00000 1 1.73143 0.24740 0.61250 0.08750 0.68575 0.15336 0.24243 0.05421 56981.888378 0.000334 0.83661 0.25232 0.95652 1 1.28155 0.26303 0.45486 0.09334 1.07216 0.23694 0.37746 0.08338 56981.889177 0.000465 0.56510 0.15708 1.00000 1 1.32233 0.22764 0.46731 0.08044 0.74726 0.16309 0.26250 0.05728 56981.890020 0.000378 0.52924 0.14813 0.96154 1 1.71587 0.28212 0.59200 0.09732 0.90810 0.20569 0.31616 0.07161 56981.890731 0.000334 0.61671 0.17758 1.00000 1 1.59465 0.28644 0.56364 0.10123 0.98343 0.22132 0.34574 0.07780 56981.891429 0.000363 0.53733 0.15181 1.00000 1 1.71535 0.30211 0.62172 0.10949 0.92172 0.20362 0.33216 0.07337 56981.892271 0.000479 0.53536 0.14650 1.00000 1 1.33044 0.21732 0.47200 0.07708 0.71226 0.15638 0.25309 0.05557 56981.893143 0.000392 0.45615 0.12601 0.96296 1 1.88707 0.29839 0.66667 0.10541 0.86078 0.19499 0.30400 0.06885 56981.893869 0.000334 0.48591 0.13788 1.00000 1 1.98809 0.34357 0.71074 0.12281 0.96602 0.21741 0.34574 0.07780 56981.894682 0.000479 0.40751 0.11013 0.96970 1 1.73137 0.25887 0.60533 0.09050 0.70556 0.15884 0.24850 0.05592 56981.895626 0.000465 0.49218 0.13330 0.96875 1 1.51228 0.23693 0.54507 0.08539 0.74432 0.16444 0.26787 0.05917 56981.896571 0.000450 0.58929 0.16121 0.96774 1 1.32656 0.21886 0.47587 0.07850 0.78173 0.17059 0.28000 0.06110 56981.897457 0.000436 0.58894 0.16962 1.00000 1 1.24837 0.22431 0.45029 0.08089 0.73522 0.16548 0.26507 0.05965 56981.898386 0.000494 0.48988 0.13162 0.94118 1 1.48217 0.23226 0.53419 0.08369 0.72608 0.15846 0.26250 0.05728 56981.899359 0.000479 0.48397 0.13028 1.00000 1 1.46524 0.22818 0.52050 0.08105 0.70913 0.15570 0.25309 0.05557 56981.900318 0.000479 0.42619 0.11224 0.93939 1 1.78494 0.26318 0.63449 0.09355 0.76073 0.16601 0.27097 0.05913 56981.901233 0.000436 0.37819 0.10031 1.00000 1 1.95456 0.27439 0.70180 0.09852 0.73919 0.16635 0.26507 0.05965 56981.902003 0.000334 0.80226 0.24209 0.95652 1 1.25593 0.25247 0.45237 0.09094 1.00759 0.22676 0.36146 0.08134 56981.902904 0.000566 0.62633 0.15444 0.93120 1 1.34068 0.20509 0.47229 0.07224 0.83970 0.16239 0.29606 0.05725 56981.962889 0.000639 0.39027 0.10431 0.95455 1 2.41679 0.34206 0.48082 0.06806 0.94320 0.21384 0.18803 0.04263 56981.964370 0.000842 0.60984 0.13451 0.99811 1 1.90262 0.26386 0.38519 0.05342 1.16030 0.19900 0.23493 0.04029
