/* ** ** 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 58249.167360 0.000434 0.38234 0.06480 0.98000 0 2.08257 0.18546 1.75693 0.15645 0.79624 0.11483 0.67003 0.09659 58249.168176 0.000382 0.44869 0.07764 0.97727 0 2.04038 0.20073 1.72054 0.16921 0.91549 0.13032 0.77217 0.10990 58249.168998 0.000440 0.40949 0.06887 0.98684 0 1.99395 0.18304 1.65377 0.15178 0.81650 0.11506 0.67742 0.09545 58249.169889 0.000451 0.39656 0.06735 0.99359 0 1.92365 0.17552 1.61228 0.14709 0.76284 0.10928 0.63904 0.09153 58249.170746 0.000399 0.40315 0.06772 0.99275 0 2.16501 0.19625 1.81777 0.16474 0.87282 0.12344 0.73114 0.10340 58249.171588 0.000443 0.35117 0.05828 0.98039 0 2.24564 0.19175 1.89496 0.16182 0.78860 0.11223 0.66406 0.09451 58249.172381 0.000350 0.45744 0.07802 1.00000 0 2.18247 0.21249 1.84595 0.17973 0.99836 0.13980 0.84438 0.11824 58249.173127 0.000396 0.39543 0.06655 0.96350 0 2.28708 0.20551 1.90634 0.17129 0.90437 0.12871 0.75462 0.10740 58249.173926 0.000402 0.40130 0.06753 0.97122 0 2.20452 0.20106 1.84262 0.16804 0.88468 0.12512 0.74198 0.10493 58249.174779 0.000451 0.41131 0.06957 0.96795 0 1.93951 0.17991 1.61262 0.14958 0.79775 0.11282 0.66336 0.09381 58249.175590 0.000359 0.43900 0.07442 0.98387 0 2.31411 0.21986 1.92282 0.18270 1.01590 0.14263 0.84474 0.11859 58249.176319 0.000370 0.51873 0.09324 0.99219 0 1.77961 0.18644 1.47710 0.15475 0.92313 0.13484 0.76677 0.11197 58249.177213 0.000524 0.31033 0.04756 0.98343 0 2.49259 0.18749 2.07115 0.15576 0.77353 0.10328 0.64338 0.08588
