/* ** ** 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 58143.498912 0.000356 0.31622 0.08251 0.99187 0 2.50862 0.33375 1.00513 0.13184 0.79327 0.17807 0.32842 0.07344 58143.499748 0.000480 0.25783 0.06830 0.94578 0 2.92664 0.34806 0.94581 0.11216 0.75457 0.17863 0.24199 0.05745 58143.500552 0.000324 0.57903 0.16342 0.94643 0 2.18744 0.37433 0.66851 0.11440 1.26660 0.28427 0.38710 0.08688 58143.501267 0.000391 0.56279 0.15597 0.98519 0 1.83522 0.31351 0.56004 0.09566 1.03284 0.22538 0.31632 0.06903 58143.501964 0.000307 0.61575 0.17743 0.97170 0 2.06208 0.37476 0.63183 0.11483 1.26973 0.28392 0.38900 0.08698 58143.502656 0.000385 0.45094 0.12679 0.98496 0 2.13184 0.33294 0.65188 0.10181 0.96134 0.22478 0.29398 0.06873 58143.503585 0.000544 0.32472 0.08516 0.97340 0 2.18017 0.28669 0.66948 0.08803 0.70794 0.16064 0.21611 0.04904 58143.504543 0.000414 0.43653 0.11660 0.93007 0 2.24774 0.32842 0.68930 0.10072 0.98121 0.21941 0.30125 0.06736 58143.505411 0.000454 0.41216 0.11277 0.96815 0 2.03473 0.30053 0.62496 0.09231 0.83864 0.19314 0.25677 0.05914 58143.506256 0.000391 0.45118 0.12206 0.94074 0 2.28461 0.34785 0.69969 0.10654 1.03078 0.23049 0.31549 0.07054 58143.507254 0.000608 0.21497 0.05314 0.98095 0 2.95299 0.31109 0.90501 0.09534 0.63482 0.14195 0.19450 0.04349 58143.508301 0.000440 0.35747 0.09392 0.99342 0 2.42573 0.33459 0.74201 0.10235 0.86712 0.19390 0.26534 0.05933 58143.509227 0.000486 0.42634 0.10193 0.95833 0 2.46005 0.32839 0.75068 0.10020 1.04881 0.20804 0.32030 0.06353
