/* ** ** 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 58188.329276 0.000486 0.33620 0.05659 0.98214 0 2.19858 0.18530 1.76593 0.14881 0.73916 0.10769 0.59145 0.08614 58188.330097 0.000336 0.67810 0.12233 0.93966 0 1.77209 0.20445 1.40993 0.16267 1.20166 0.16664 0.95572 0.13253 58188.330835 0.000402 0.50038 0.08789 0.97842 0 1.84564 0.19018 1.46381 0.15084 0.92352 0.13137 0.73273 0.10423 58188.331805 0.000567 0.32188 0.05345 0.96939 0 2.03308 0.16840 1.61298 0.13360 0.65440 0.09418 0.51905 0.07470 58188.332809 0.000437 0.44130 0.07466 0.96689 0 1.99982 0.18983 1.58584 0.15054 0.88253 0.12358 0.69980 0.09799 58188.333633 0.000388 0.45134 0.07893 0.98507 0 2.08895 0.20485 1.64923 0.16174 0.94283 0.13652 0.74322 0.10760 58188.334499 0.000477 0.38581 0.06476 0.97576 0 2.04351 0.18208 1.60515 0.14301 0.78840 0.11215 0.61895 0.08804 58188.335433 0.000457 0.47765 0.08469 0.97468 0 1.69017 0.17498 1.34149 0.13889 0.80731 0.11622 0.64039 0.09217 58188.336272 0.000382 0.51944 0.09168 0.96212 0 1.96519 0.20478 1.52633 0.15903 1.02081 0.14542 0.79231 0.11287 58188.337082 0.000428 0.48267 0.08420 0.98649 0 1.81332 0.18467 1.43632 0.14628 0.87524 0.12397 0.69273 0.09812 58188.337838 0.000327 0.54781 0.10003 0.99115 0 2.01469 0.22190 1.59033 0.17517 1.10367 0.16074 0.87133 0.12690 58188.339206 0.001036 0.33722 0.04255 0.94693 0 1.91469 0.12161 1.50012 0.09526 0.64567 0.07040 0.50653 0.05523
