/* ** ** 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 55225.567771 0.000952 0.44907 0.03845 0.97264 0 3.35412 0.15927 2.76959 0.13152 1.50622 0.10730 1.24393 0.08861 55225.570132 0.001409 0.49328 0.03429 0.97854 0 3.20632 0.12752 2.66654 0.10605 1.58161 0.09017 1.31509 0.07498 55225.633908 0.000411 0.43087 0.06278 0.96479 0 3.07799 0.24564 2.31249 0.18437 1.32622 0.16168 0.99063 0.12064 55225.634678 0.000359 0.30579 0.04976 0.94355 0 3.67858 0.29070 2.79301 0.22071 1.12488 0.16002 0.85176 0.12115 55225.635346 0.000310 0.39808 0.06648 0.96262 0 3.22631 0.28971 2.47894 0.22260 1.28432 0.18086 0.98698 0.13899 55225.636561 0.000906 0.51662 0.04536 0.95208 0 3.38646 0.17289 2.58078 0.13174 1.74950 0.12498 1.33252 0.09518 55225.637762 0.000295 0.35728 0.06049 0.99020 0 3.58454 0.30987 2.72150 0.23523 1.28069 0.18642 0.96646 0.14071 55225.639174 0.001117 0.43263 0.03665 0.97150 0 3.22379 0.14992 2.46292 0.11453 1.39470 0.09876 1.06708 0.07556 55225.641339 0.001047 0.48120 0.04113 0.97558 0 3.19846 0.15572 2.43432 0.11851 1.53909 0.10813 1.17245 0.08237 55225.707012 0.000446 0.55518 0.10000 0.98052 0 3.91911 0.42876 1.18881 0.13006 2.17581 0.31132 0.65651 0.09394 55225.707900 0.000443 0.51578 0.09000 0.93464 0 4.38668 0.44325 1.35622 0.13702 2.26258 0.32185 0.69685 0.09913 55225.708829 0.000486 0.43986 0.07351 0.95238 0 4.76262 0.43853 1.46822 0.13518 2.09490 0.29220 0.64785 0.09035 55225.709822 0.000506 0.50947 0.08950 0.96571 0 3.73241 0.38482 1.15505 0.11906 1.90156 0.27048 0.58964 0.08388 55225.710927 0.000599 0.43478 0.07517 0.95169 0 3.70291 0.35464 1.14916 0.11001 1.60994 0.23175 0.50059 0.07205 55225.712018 0.000492 0.43280 0.07483 0.97647 0 4.44894 0.43164 1.37864 0.13374 1.92550 0.27557 0.59718 0.08545 55225.712880 0.000370 0.62279 0.11191 0.95312 0 4.23352 0.46909 1.32684 0.14693 2.63658 0.37297 0.82104 0.11611 55225.713896 0.000645 0.41606 0.06112 0.95516 0 4.79487 0.38716 1.50850 0.12179 1.99494 0.24483 0.62773 0.07702
