/* ** ** 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 57610.291947 0.001050 0.43532 0.03731 0.98623 0 2.98076 0.14087 2.54788 0.12040 1.29758 0.09277 1.10839 0.07924 57610.293957 0.000961 0.52765 0.04655 0.97289 0 2.72035 0.14139 2.33680 0.12145 1.43539 0.10231 1.23191 0.08780 57610.295948 0.001030 0.52468 0.04629 0.99157 0 2.53028 0.13236 2.15985 0.11297 1.32758 0.09433 1.13034 0.08030 57610.298095 0.001117 0.43313 0.03729 0.97927 0 2.80582 0.13465 2.42350 0.11630 1.21528 0.08688 1.04974 0.07505 57610.299530 0.000318 0.39933 0.06763 0.98182 0 2.67373 0.24545 2.30996 0.21206 1.06770 0.15195 0.92236 0.13126 57610.300158 0.000310 0.39205 0.06572 0.95327 0 2.88357 0.25544 2.49024 0.22060 1.13051 0.16089 0.97662 0.13899 57610.300789 0.000321 0.36759 0.05893 1.00000 0 3.09217 0.26051 2.67028 0.22497 1.13664 0.15503 0.98270 0.13403 57610.301420 0.000310 0.42098 0.07079 0.98131 0 2.69496 0.24733 2.30093 0.21115 1.13454 0.15985 0.96779 0.13636 57610.302048 0.000318 0.38706 0.06549 0.99091 0 2.71933 0.24507 2.34680 0.21149 1.05254 0.15074 0.90883 0.13016 57610.303599 0.001233 0.40472 0.03310 0.98826 0 2.92972 0.12962 2.52290 0.11161 1.18572 0.08155 1.02080 0.07021
