/* ** ** 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 58190.321888 0.000350 0.37629 0.10281 0.98347 0 2.44058 0.34487 0.86883 0.12236 0.91835 0.21475 0.32367 0.07566 58190.322730 0.000492 0.30109 0.07717 0.95294 0 2.57769 0.32133 0.81767 0.10186 0.77610 0.17381 0.24733 0.05530 58190.323705 0.000483 0.34330 0.08999 0.94012 0 2.45395 0.33565 0.74212 0.10150 0.84245 0.18838 0.25520 0.05706 58190.324541 0.000353 0.68703 0.19506 0.95082 0 1.84806 0.33895 0.55892 0.10252 1.26968 0.27518 0.38385 0.08318 58190.325302 0.000402 0.43485 0.11684 0.97122 0 2.35215 0.35856 0.70735 0.10783 1.02283 0.22633 0.30780 0.06811 58190.326051 0.000347 0.50119 0.13828 0.97500 0 2.26196 0.36561 0.68334 0.11045 1.13368 0.25350 0.34245 0.07657 58190.326893 0.000495 0.30502 0.08062 0.95322 0 2.59955 0.33725 0.78532 0.10186 0.79290 0.18258 0.23947 0.05515 58190.327758 0.000370 0.42960 0.11622 0.97656 0 2.47897 0.37745 0.74642 0.11364 1.06496 0.23813 0.32053 0.07167 58190.328470 0.000341 0.46296 0.12862 0.94915 0 2.48863 0.38670 0.75336 0.11706 1.15214 0.26533 0.34851 0.08026 58190.329199 0.000388 0.48052 0.13337 0.92537 0 2.19503 0.35081 0.66306 0.10597 1.05476 0.23934 0.31895 0.07237 58190.330059 0.000466 0.34831 0.09080 0.96894 0 2.43403 0.32614 0.73630 0.09866 0.84779 0.18957 0.25684 0.05743 58190.330869 0.000344 0.40394 0.10663 0.98319 0 2.91413 0.41943 0.88051 0.12673 1.17712 0.26048 0.35516 0.07859 58190.331624 0.000411 0.48348 0.13321 0.97183 0 1.99706 0.32146 0.60030 0.09663 0.96553 0.21590 0.29034 0.06492 58190.332776 0.000735 0.65113 0.12068 0.95669 0 2.10442 0.25207 0.63322 0.07587 1.37026 0.19379 0.41221 0.05830 58190.334118 0.000608 0.46486 0.10257 0.97143 0 2.15049 0.27039 0.64983 0.08170 0.99969 0.18125 0.30190 0.05474
