/* ** ** 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 58193.310401 0.000414 0.46396 0.07927 0.95804 0 1.94169 0.18781 1.59244 0.15404 0.90087 0.12687 0.74202 0.10450 58193.311116 0.000301 0.53567 0.09569 1.00000 0 2.22123 0.24237 1.79899 0.19627 1.18985 0.16828 0.96314 0.13621 58193.311834 0.000417 0.44043 0.07562 0.97917 0 1.97158 0.18960 1.60442 0.15429 0.86834 0.12351 0.70676 0.10053 58193.312606 0.000356 0.48912 0.08532 0.99187 0 2.06483 0.21086 1.67560 0.17112 1.00994 0.14283 0.82104 0.11611 58193.313338 0.000376 0.40699 0.06943 0.95385 0 2.41043 0.22393 1.96518 0.18256 0.98102 0.14035 0.79952 0.11439 58193.314082 0.000367 0.41365 0.07092 0.99213 0 2.37325 0.22933 1.94089 0.18756 0.98170 0.13904 0.80273 0.11369 58193.314782 0.000333 0.53606 0.09452 0.98261 0 2.09224 0.22416 1.69272 0.18133 1.12157 0.15706 0.90416 0.12661 58193.315482 0.000367 0.47833 0.08260 0.94488 0 2.13376 0.20891 1.73579 0.16995 1.02063 0.14518 0.83045 0.11812 58193.316186 0.000336 0.46853 0.08152 0.97414 0 2.30841 0.23134 1.88209 0.18861 1.08155 0.15384 0.88189 0.12544 58193.316825 0.000304 0.55222 0.09866 0.98095 0 2.15173 0.23260 1.75219 0.18941 1.18823 0.16902 0.96751 0.13762 58193.317543 0.000414 0.32429 0.05409 0.97203 0 2.68436 0.22628 2.18824 0.18446 0.87050 0.12528 0.70955 0.10211 58193.318385 0.000428 0.41723 0.07090 0.93919 0 2.09825 0.19235 1.71000 0.15676 0.87546 0.12525 0.71324 0.10205 58193.319227 0.000414 0.47188 0.08166 0.97203 0 1.87546 0.18704 1.52659 0.15224 0.88499 0.12516 0.72062 0.10191 58193.320022 0.000382 0.48094 0.08415 0.96970 0 1.97694 0.19912 1.61010 0.16217 0.95079 0.13603 0.77454 0.11081 58193.320942 0.000538 0.44485 0.06559 0.95699 0 2.11276 0.17357 1.71956 0.14127 0.93986 0.11507 0.76505 0.09367
