/* ** ** 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 57093.071209 0.000596 0.37040 0.09766 1.00000 1 2.31460 0.31678 0.52409 0.07172 0.85733 0.19320 0.19375 0.04365 57093.072298 0.000494 0.43294 0.11596 0.97059 1 2.44002 0.35978 0.55758 0.08221 1.05639 0.23622 0.24242 0.05421 57093.073213 0.000421 0.54642 0.15044 0.96552 1 2.40624 0.39888 0.54399 0.09016 1.31482 0.28903 0.29800 0.06550 57093.074085 0.000450 0.59819 0.17337 0.96774 1 1.90726 0.33506 0.43626 0.07664 1.14090 0.26300 0.25919 0.05975 57093.075101 0.000566 0.44481 0.11409 0.96956 1 2.34438 0.33121 0.53505 0.07559 1.04280 0.22325 0.23737 0.05082 57093.429109 0.102087 0.24650 0.16109 0.02402 1 0.89558 0.54993 0.07752 0.01362 0.22076 0.04937 0.04738 0.01059 57093.531762 0.000566 0.38114 0.10183 0.97436 1 2.54078 0.36480 0.54778 0.07864 0.96840 0.21818 0.20905 0.04710 57093.532808 0.000479 0.57106 0.16372 0.93939 1 2.06231 0.36564 0.44745 0.07933 1.17770 0.26533 0.25626 0.05773 57093.533796 0.000508 0.64586 0.18929 0.97143 1 1.65730 0.30718 0.35855 0.06646 1.07038 0.24301 0.23200 0.05266 57093.534900 0.000596 0.42122 0.11027 0.97561 1 2.29329 0.33167 0.49682 0.07185 0.96598 0.21080 0.21000 0.04583 57093.536120 0.000625 0.33220 0.08607 1.00000 1 2.58210 0.33787 0.55924 0.07318 0.85777 0.19180 0.18605 0.04160 57093.537166 0.000421 0.59982 0.16807 0.96552 1 2.29429 0.39872 0.49748 0.08646 1.37615 0.30248 0.29800 0.06550 57093.538096 0.000508 0.48675 0.13423 1.00000 1 2.17745 0.35136 0.46933 0.07574 1.05988 0.23701 0.22857 0.05111 57093.539141 0.000537 0.42136 0.11356 0.97297 1 2.41439 0.35716 0.52412 0.07753 1.01731 0.22919 0.22067 0.04971 57093.540405 0.000726 0.25647 0.06463 0.94000 1 3.04977 0.34418 0.66083 0.07458 0.78218 0.17622 0.16902 0.03808 57093.541509 0.000378 0.56763 0.15859 0.88462 1 2.77808 0.45245 0.60576 0.09866 1.57693 0.35799 0.34296 0.07785 57093.542584 0.000697 0.48384 0.13261 0.95833 1 1.65638 0.26251 0.35947 0.05697 0.80142 0.17921 0.17391 0.03889 57093.544153 0.000872 0.25486 0.06445 0.98333 1 2.43589 0.27978 0.52717 0.06055 0.62081 0.13986 0.13464 0.03033 57093.545780 0.000755 0.50897 0.11257 0.93087 1 2.30491 0.29180 0.49773 0.06301 1.17312 0.21275 0.25386 0.04604
