/* ** ** 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 57586.510585 0.000399 0.46266 0.06986 0.96377 0 2.47890 0.21081 2.12240 0.18047 1.14689 0.14310 0.98230 0.12256 57586.511326 0.000341 0.38346 0.06281 0.96610 0 2.78293 0.24256 2.37811 0.20727 1.06714 0.14799 0.91380 0.12672 57586.512058 0.000391 0.37727 0.06290 0.95556 0 2.37214 0.20623 2.04742 0.17800 0.89493 0.12732 0.77242 0.10989 57586.512798 0.000350 0.35822 0.06118 0.97521 0 2.65835 0.23287 2.29528 0.20107 0.95228 0.13961 0.82219 0.12054 57586.513548 0.000399 0.31897 0.05254 0.97826 0 2.66890 0.21772 2.30118 0.18772 0.85129 0.12183 0.73420 0.10508 57586.514271 0.000324 0.41014 0.06743 0.93750 0 2.80355 0.24758 2.41925 0.21364 1.14985 0.15946 0.99213 0.13758 57586.514951 0.000356 0.35799 0.05972 0.95935 0 2.71860 0.23299 2.34644 0.20109 0.97322 0.13928 0.83998 0.12021 57586.515692 0.000385 0.32537 0.05337 0.97744 0 2.72951 0.22282 2.35571 0.19231 0.88809 0.12634 0.76648 0.10904 57586.516427 0.000350 0.37508 0.06267 0.95868 0 2.64135 0.22778 2.27760 0.19641 0.99073 0.14179 0.85446 0.12229 57586.517483 0.000706 0.40234 0.04379 0.99590 0 2.85992 0.16922 2.46860 0.14607 1.15066 0.10512 0.99323 0.09074 57586.518548 0.000359 0.32268 0.05222 0.98387 0 3.00680 0.24397 2.59536 0.21059 0.97022 0.13586 0.83746 0.11727 57586.519219 0.000312 0.49506 0.08735 0.98148 0 2.18794 0.22578 1.88876 0.19491 1.08316 0.15502 0.93507 0.13382 57586.519896 0.000365 0.37500 0.06331 0.98413 0 2.46943 0.22111 2.13157 0.19086 0.92603 0.13253 0.79933 0.11440 57586.520576 0.000315 0.45167 0.07812 0.99083 0 2.37852 0.23399 2.04002 0.20069 1.07431 0.15284 0.92261 0.13125 57586.521198 0.000307 0.42902 0.07452 0.99057 0 2.53513 0.24635 2.18883 0.21270 1.08763 0.15659 0.93898 0.13519 57586.521826 0.000321 0.44803 0.07673 0.96396 0 2.45618 0.23933 2.12028 0.20660 1.10045 0.15499 0.94996 0.13380 57586.522442 0.000295 0.49830 0.08755 1.00000 0 2.27047 0.23412 1.96040 0.20215 1.13137 0.16095 0.97688 0.13897 57586.523073 0.000336 0.45304 0.07838 0.95690 0 2.29750 0.22334 1.97352 0.19178 1.04086 0.14896 0.89295 0.12779 57586.523733 0.000324 0.42872 0.07101 0.97321 0 2.64204 0.24060 2.28121 0.20774 1.13270 0.15671 0.97804 0.13532 57586.524520 0.000463 0.45537 0.06461 0.97500 0 2.40002 0.19202 2.07206 0.16578 1.09291 0.12807 0.94357 0.11057
