/* ** ** 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 58162.425632 0.000498 0.38901 0.06489 0.97093 0 1.77820 0.15730 1.54252 0.13645 0.69174 0.09783 0.59980 0.08482 58162.426428 0.000298 0.35252 0.09261 0.98058 0 1.29790 0.17895 1.12539 0.15516 0.45753 0.10231 0.39670 0.08870 58162.427290 0.000564 0.40943 0.06882 0.96923 0 1.50182 0.13641 1.29234 0.11739 0.61489 0.08696 0.52998 0.07495 58162.428323 0.000469 0.38251 0.06432 0.98765 0 1.87772 0.16823 1.62760 0.14582 0.71824 0.10220 0.62269 0.08860 58162.429359 0.000567 0.40176 0.06719 0.97959 0 1.52774 0.13766 1.32008 0.11893 0.61378 0.08647 0.52934 0.07457 58162.430450 0.000524 0.42735 0.07289 0.96685 0 1.53996 0.14473 1.33392 0.12537 0.65811 0.09366 0.56932 0.08100 58162.431521 0.000547 0.43260 0.07326 0.95767 0 1.47559 0.13749 1.27902 0.11917 0.63834 0.09028 0.55341 0.07826 58162.432617 0.000550 0.40631 0.06934 0.98421 0 1.50363 0.13970 1.30420 0.12117 0.61094 0.08746 0.52991 0.07586 58162.433665 0.000498 0.41176 0.06992 0.97093 0 1.67204 0.15496 1.44885 0.13427 0.68847 0.09796 0.59659 0.08489 58162.434692 0.000530 0.37100 0.06220 0.97814 0 1.72110 0.15015 1.49292 0.13024 0.63853 0.09141 0.55360 0.07925 58162.435786 0.000564 0.37737 0.06279 0.97949 0 1.61078 0.14118 1.39064 0.12188 0.60786 0.08597 0.52443 0.07417 58162.436926 0.000576 0.40060 0.06615 0.98492 0 1.53507 0.13763 1.32570 0.11886 0.61495 0.08528 0.53150 0.07371
