/* ** ** 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 56408.522441 0.000431 0.33738 0.05674 0.97987 0 2.33743 0.19610 1.98082 0.16619 0.78861 0.11495 0.66788 0.09737 56408.523294 0.000422 0.31867 0.05205 0.97260 0 2.61549 0.21365 2.21689 0.18107 0.83347 0.11788 0.70540 0.09976 56408.524015 0.000298 0.52116 0.09201 0.98058 0 2.20798 0.22821 1.88312 0.19463 1.15070 0.16471 0.98123 0.14045 56408.524663 0.000350 0.40308 0.06406 0.95041 0 2.86666 0.24559 2.44052 0.20909 1.15548 0.15468 0.98372 0.13168 56408.525363 0.000350 0.41895 0.07158 0.95041 0 2.40295 0.22089 2.04594 0.18807 1.00673 0.14498 0.85715 0.12344 56408.526159 0.000446 0.37249 0.06104 0.96753 0 2.16215 0.18404 1.84088 0.15670 0.80538 0.11278 0.68571 0.09602 56408.526995 0.000391 0.32542 0.05346 0.99259 0 2.72137 0.22621 2.31838 0.19271 0.88559 0.12548 0.75453 0.10691 56408.527918 0.000532 0.41000 0.05272 0.97283 0 2.81079 0.19543 2.38609 0.16590 1.15241 0.12467 0.97826 0.10583 56408.528786 0.000336 0.34781 0.05756 0.98276 0 2.96711 0.25076 2.51168 0.21226 1.03200 0.14683 0.87399 0.12435 56408.529475 0.000353 0.45433 0.07280 0.95902 0 2.53194 0.22482 2.15598 0.19144 1.15033 0.15343 0.97948 0.13064 56408.530554 0.000726 0.32065 0.03803 0.98369 0 2.81694 0.16446 2.38630 0.13931 0.90324 0.09326 0.76650 0.07914
