/* ** ** 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 58580.290305 0.000469 0.34754 0.05774 0.97531 0 2.31222 0.19886 1.80505 0.15518 0.80358 0.11422 0.63125 0.08970 58580.291300 0.000527 0.35609 0.05903 0.96154 0 2.02844 0.17537 1.60363 0.13865 0.72232 0.10216 0.57238 0.08095 58580.292333 0.000506 0.30347 0.04969 0.95429 0 2.44972 0.19336 1.95082 0.15398 0.74341 0.10665 0.59209 0.08494 58580.293320 0.000480 0.34511 0.05676 0.95783 0 2.29586 0.19282 1.82672 0.15342 0.79233 0.11205 0.62998 0.08909 58580.294275 0.000475 0.38752 0.06503 0.96951 0 2.05599 0.18566 1.62233 0.14651 0.79674 0.11268 0.62998 0.08909 58580.295154 0.000405 0.43863 0.07533 0.97857 0 2.08374 0.20100 1.65946 0.16007 0.91398 0.12987 0.72801 0.10345 58580.296014 0.000454 0.41060 0.06988 0.98089 0 1.99933 0.18925 1.58205 0.14973 0.82092 0.11610 0.65043 0.09199 58580.296992 0.000524 0.30706 0.05016 0.98343 0 2.29575 0.18496 1.82321 0.14689 0.70494 0.10017 0.56032 0.07962 58580.298039 0.000524 0.37501 0.06343 0.96133 0 1.92497 0.17245 1.51963 0.13608 0.72188 0.10356 0.56827 0.08152 58580.299260 0.000697 0.46403 0.06390 0.96680 0 1.87343 0.14811 1.48032 0.11702 0.86932 0.09803 0.68722 0.07749
