/* ** ** 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 58500.468685 0.000394 0.42669 0.07313 0.99265 0 2.05124 0.19425 1.72621 0.16346 0.87524 0.12502 0.73532 0.10504 58500.469600 0.000515 0.27117 0.04358 0.98315 0 2.52992 0.18959 2.10593 0.15780 0.68604 0.09752 0.56981 0.08099 58500.470433 0.000318 0.57401 0.10197 0.97273 0 1.95680 0.20863 1.64257 0.17509 1.12323 0.15961 0.94226 0.13390 58500.471142 0.000391 0.39178 0.06648 0.97037 0 2.29611 0.20494 1.91943 0.17131 0.89957 0.12981 0.75091 0.10835 58500.471932 0.000399 0.36415 0.06116 0.97101 0 2.41082 0.21016 2.02642 0.17666 0.87790 0.12604 0.73745 0.10587 58500.472803 0.000472 0.33117 0.05488 0.96933 0 2.25298 0.18638 1.88817 0.15621 0.74612 0.10713 0.62543 0.08979 58500.473616 0.000341 0.46591 0.07590 0.95763 0 2.55501 0.23368 2.11534 0.19348 1.19041 0.16049 0.98485 0.13279 58500.474325 0.000367 0.41695 0.07178 0.99213 0 2.23812 0.21004 1.87378 0.17583 0.93318 0.13468 0.78071 0.11265 58500.475080 0.000388 0.35867 0.05943 0.99254 0 2.55804 0.22091 2.09980 0.18133 0.91748 0.12975 0.75313 0.10651 58500.475803 0.000336 0.47005 0.08082 0.97414 0 2.30926 0.22580 1.90640 0.18641 1.08546 0.15351 0.89621 0.12673 58500.476483 0.000344 0.43838 0.07637 0.98319 0 2.30784 0.22525 1.92232 0.18759 1.01172 0.14600 0.84076 0.12132 58500.477244 0.000417 0.40562 0.07033 0.96528 0 2.09271 0.19637 1.72928 0.16226 0.84884 0.12376 0.70123 0.10222 58500.478411 0.000749 0.32174 0.04164 0.96911 0 2.41306 0.15444 1.99502 0.12769 0.77637 0.08732 0.64373 0.07241
