/* ** ** 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 57149.491032 0.000422 0.37485 0.06274 0.98630 0 2.16545 0.19140 1.84734 0.16328 0.81172 0.11537 0.69247 0.09842 57149.491830 0.000376 0.34668 0.05736 0.96154 0 2.69303 0.22482 2.28527 0.19077 0.93362 0.13337 0.79411 0.11344 57149.492577 0.000370 0.34951 0.05759 1.00000 0 2.66542 0.22529 2.24374 0.18963 0.93158 0.13175 0.78255 0.11067 57149.493355 0.000408 0.35154 0.05808 0.97872 0 2.43339 0.20495 2.05486 0.17305 0.85543 0.12159 0.72257 0.10270 57149.494238 0.000475 0.32978 0.05449 0.98171 0 2.24644 0.18654 1.87332 0.15555 0.74082 0.10584 0.61654 0.08808 57149.495106 0.000394 0.41935 0.07015 0.94853 0 2.25878 0.20665 1.88319 0.17227 0.94721 0.13265 0.79202 0.11090 57149.495904 0.000405 0.39943 0.06715 0.99286 0 2.12057 0.19275 1.80149 0.16375 0.84702 0.11979 0.72062 0.10191 57149.496685 0.000376 0.33833 0.05630 0.98462 0 2.71464 0.22822 2.28034 0.19169 0.91845 0.13190 0.77197 0.11084 57149.497530 0.000469 0.27535 0.04433 0.99383 0 2.68456 0.20293 2.24703 0.16986 0.73919 0.10508 0.61935 0.08803 57149.498398 0.000399 0.40231 0.06903 0.97826 0 2.12720 0.19500 1.79550 0.16459 0.85579 0.12413 0.72525 0.10520 57149.499298 0.000501 0.35953 0.05960 0.97110 0 1.97242 0.16821 1.65272 0.14094 0.70915 0.10080 0.59354 0.08436 57149.500218 0.000420 0.40965 0.06855 0.98621 0 2.07640 0.18800 1.73667 0.15723 0.85060 0.11970 0.71132 0.10010 57149.501101 0.000463 0.30427 0.04993 0.98750 0 2.44683 0.19437 2.05922 0.16356 0.74451 0.10690 0.62539 0.08979 57149.502033 0.000469 0.31680 0.05131 0.96296 0 2.44999 0.19341 2.05244 0.16201 0.77616 0.10977 0.64915 0.09180 57149.502973 0.000472 0.38155 0.06152 0.95706 0 2.15995 0.18454 1.81328 0.15489 0.82413 0.11269 0.69057 0.09441
