/* ** ** 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 58243.190153 0.000463 0.43348 0.07497 0.98125 0 1.71895 0.16358 1.44787 0.13777 0.74512 0.10761 0.62610 0.09042 58243.191284 0.000668 0.35959 0.06034 0.97403 0 1.44340 0.12521 1.22014 0.10584 0.51903 0.07456 0.43896 0.06306 58243.192271 0.000318 0.33204 0.08481 0.96364 0 1.39047 0.17816 1.18205 0.15145 0.46169 0.10201 0.39248 0.08672 58243.193047 0.000457 0.43046 0.07359 0.97468 0 1.76836 0.16792 1.50385 0.14280 0.76120 0.10821 0.64740 0.09204 58243.193949 0.000446 0.50896 0.09005 0.97403 0 1.53461 0.16008 1.30057 0.13568 0.78106 0.11162 0.66155 0.09454 58243.194693 0.000298 0.25299 0.06377 0.99029 0 1.85373 0.21562 1.55635 0.18104 0.46897 0.10487 0.39281 0.08784 58243.195564 0.000573 0.32925 0.05378 0.97475 0 1.87568 0.15319 1.59283 0.13009 0.61756 0.08737 0.52454 0.07421 58243.196441 0.000304 0.21473 0.05331 0.96190 0 2.17248 0.23439 1.84730 0.19931 0.46649 0.10431 0.39670 0.08870 58243.197106 0.000362 0.80311 0.15259 0.94400 0 1.23740 0.15598 1.05203 0.13261 0.99376 0.14127 0.84491 0.12011 58243.197928 0.000460 0.48231 0.08420 0.98742 0 1.54913 0.15698 1.31668 0.13343 0.74717 0.10622 0.63503 0.09028 58243.198828 0.000440 0.46799 0.08138 0.98026 0 1.69045 0.16747 1.42401 0.14110 0.79112 0.11307 0.66599 0.09518 58243.199768 0.000501 0.43605 0.07423 0.93642 0 1.67889 0.15909 1.41728 0.13430 0.73208 0.10354 0.61831 0.08744 58243.200819 0.000550 0.37540 0.06030 0.97368 0 1.87229 0.16153 1.57913 0.13622 0.70285 0.09522 0.59306 0.08035
