/* ** ** 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 55894.631047 0.000330 0.43552 0.07415 0.99123 0 2.38239 0.22581 2.03746 0.19310 1.03758 0.14674 0.88643 0.12536 55894.631733 0.000356 0.42938 0.07341 0.96748 0 2.27163 0.21247 1.93559 0.18102 0.97538 0.13960 0.83293 0.11920 55894.632442 0.000353 0.33642 0.05733 0.99180 0 2.76462 0.23616 2.37477 0.20284 0.93007 0.13715 0.79752 0.11763 55894.633110 0.000315 0.50685 0.08871 0.98165 0 2.12427 0.21654 1.83731 0.18729 1.07669 0.15317 0.93124 0.13248 55894.633831 0.000405 0.40147 0.06844 0.96429 0 2.10496 0.19211 1.81934 0.16604 0.84507 0.12167 0.73033 0.10515 55894.634540 0.000304 0.48809 0.08408 0.98095 0 2.34971 0.23308 2.02207 0.20056 1.14687 0.16153 0.98686 0.13899 55894.635240 0.000396 0.37846 0.06344 0.95620 0 2.32649 0.20304 2.00196 0.17470 0.88048 0.12600 0.75663 0.10828 55894.636079 0.000443 0.32975 0.05411 1.00000 0 2.31208 0.19238 1.98210 0.16490 0.76241 0.10783 0.65468 0.09259 55894.636881 0.000359 0.44410 0.06886 0.99194 0 2.59596 0.22469 2.22388 0.19249 1.15286 0.14833 0.98926 0.12728 55894.637656 0.000417 0.32225 0.05266 0.96528 0 2.63269 0.21159 2.22480 0.17880 0.84838 0.12070 0.71686 0.10198 55894.638449 0.000376 0.34645 0.05635 0.98462 0 2.70902 0.22404 2.30408 0.19054 0.93854 0.13143 0.79820 0.11177 55894.639170 0.000339 0.39338 0.06669 0.98291 0 2.55393 0.22842 2.18800 0.19565 1.00465 0.14468 0.85735 0.12343 55894.639803 0.000295 0.49643 0.08769 0.99020 0 2.32828 0.23823 1.97159 0.20176 1.15583 0.16642 0.97619 0.14054 55894.640422 0.000324 0.41171 0.06961 0.98214 0 2.62708 0.24344 2.21736 0.20545 1.08160 0.15297 0.91061 0.12878 55894.641510 0.000764 0.32524 0.03941 0.96970 0 2.57932 0.15525 2.17779 0.13107 0.83889 0.08823 0.71008 0.07468
