/* ** ** 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 56036.154879 0.000347 0.43873 0.07680 0.98333 0 4.40437 0.43346 1.89798 0.18293 1.93233 0.27973 0.84887 0.12005 56036.155626 0.000399 0.39586 0.06632 0.97101 0 4.89599 0.44264 1.97464 0.17740 1.93813 0.27335 0.76246 0.10677 56036.156474 0.000448 0.40877 0.06924 0.98065 0 4.56860 0.41974 1.60839 0.14777 1.86752 0.26573 0.65554 0.09326 56036.157319 0.000396 0.60149 0.10719 0.96350 0 3.61339 0.39826 1.28858 0.14201 2.17342 0.30435 0.77402 0.10838 56036.158161 0.000446 0.39721 0.06735 0.98701 0 4.59200 0.41742 1.64559 0.14959 1.82398 0.26106 0.65209 0.09332 56036.159107 0.000501 0.38312 0.06458 0.96532 0 4.29776 0.38246 1.55566 0.13842 1.64655 0.23573 0.59352 0.08494 56036.160137 0.000530 0.35608 0.05937 0.95628 0 4.47194 0.38886 1.59651 0.13881 1.59235 0.22655 0.56938 0.08100 56036.161066 0.000399 0.52221 0.09126 0.97826 0 4.09864 0.42851 1.45092 0.15169 2.14037 0.29971 0.75682 0.10598 56036.161908 0.000443 0.50911 0.08947 0.96078 0 3.68675 0.37582 1.32485 0.13505 1.87697 0.26870 0.67427 0.09650 56036.162828 0.000477 0.41729 0.07092 0.97576 0 4.18730 0.38937 1.48288 0.13789 1.74732 0.24858 0.61889 0.08805 56036.163797 0.000492 0.43340 0.07427 0.96471 0 3.93930 0.37632 1.39886 0.13362 1.70727 0.24288 0.60757 0.08644 56036.164784 0.000495 0.39327 0.06544 0.94737 0 4.54996 0.40149 1.60989 0.14206 1.78936 0.25245 0.63333 0.08935
