/* ** ** 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 60059.599593 0.000537 0.45715 0.12389 1.00000 1 1.94925 0.29840 0.47612 0.07288 0.89110 0.19928 0.21622 0.04835 60059.600741 0.000610 0.52884 0.14774 0.97619 1 1.51417 0.25354 0.36770 0.06156 0.80075 0.17907 0.19512 0.04363 60059.601961 0.000610 0.57317 0.16264 0.97619 1 1.39673 0.24069 0.33851 0.05833 0.80056 0.18047 0.19367 0.04365 60059.603254 0.000683 0.39028 0.10357 0.97872 1 1.81639 0.25435 0.44348 0.06210 0.70891 0.15980 0.17262 0.03891 60059.604605 0.000668 0.44265 0.12097 0.93477 1 1.72050 0.26128 0.41621 0.06321 0.76157 0.17305 0.18327 0.04165 60059.605926 0.000654 0.35292 0.09270 1.00000 1 2.09329 0.28842 0.50334 0.06935 0.73876 0.16521 0.17778 0.03975 60059.607030 0.000450 0.54219 0.15096 0.96774 1 2.05158 0.34025 0.48935 0.08115 1.11234 0.24877 0.26667 0.05963 60059.608599 0.001118 0.37877 0.08077 0.95070 1 1.86075 0.21114 0.44486 0.05047 0.70479 0.12726 0.16857 0.03043
