/* ** ** 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 54887.424549 0.000365 0.46155 0.11455 0.96032 0 2.69342 0.37927 0.85410 0.12014 1.24315 0.25406 0.39736 0.08111 54887.425250 0.000330 0.47331 0.12373 0.97368 0 2.71404 0.41049 0.83398 0.12618 1.28458 0.27390 0.39706 0.08465 54887.425927 0.000347 0.41982 0.10957 0.98333 0 2.80052 0.40087 0.85452 0.12228 1.17571 0.25659 0.35653 0.07780 54887.426902 0.000628 0.53778 0.09456 0.94009 0 3.02926 0.31543 0.91995 0.09578 1.62908 0.23082 0.49573 0.07022 54887.427871 0.000341 0.35099 0.08685 0.98305 0 3.72284 0.47964 1.11494 0.14364 1.30666 0.27604 0.39272 0.08295 54887.428540 0.000327 0.43892 0.11930 0.93805 0 2.83238 0.43765 0.86027 0.13291 1.24318 0.27799 0.37799 0.08452 54887.429173 0.000307 0.49505 0.13660 0.97170 0 2.57064 0.41559 0.78570 0.12702 1.27260 0.28457 0.38900 0.08698 54887.429781 0.000301 0.35945 0.09424 0.97115 0 3.64031 0.49814 1.10989 0.15186 1.30853 0.29262 0.39670 0.08870 54887.430426 0.000344 0.48587 0.13416 0.96639 0 2.30346 0.36231 0.70970 0.11164 1.11918 0.25398 0.34388 0.07804 54887.431456 0.000686 0.40452 0.06907 0.96203 0 3.56191 0.33163 1.06892 0.09952 1.44086 0.20623 0.43476 0.06221 54887.432822 0.000680 0.48231 0.08486 0.95319 0 3.02480 0.30569 0.91224 0.09218 1.45889 0.21010 0.44020 0.06337 54887.433823 0.000321 0.41899 0.11458 0.96396 0 2.89537 0.42691 0.86937 0.12818 1.21312 0.27940 0.36472 0.08401 54887.434712 0.000567 0.52312 0.09204 0.96429 0 3.33075 0.34472 1.00607 0.10412 1.74240 0.24794 0.52723 0.07500 54887.435594 0.000315 0.40788 0.10654 0.97248 0 3.24259 0.46543 0.97161 0.13945 1.32258 0.28863 0.39689 0.08661 54887.436312 0.000402 0.31599 0.08145 0.98561 0 3.08698 0.39577 0.92605 0.11873 0.97546 0.21812 0.29246 0.06540 54887.437093 0.000379 0.28369 0.07224 0.98473 0 3.63130 0.44231 1.09440 0.13329 1.03015 0.23036 0.31059 0.06945 54887.438172 0.000700 0.56285 0.09107 0.96281 0 3.03712 0.29550 0.92360 0.08985 1.70944 0.22101 0.52001 0.06723
