/* ** ** Swift/XRT hardness ratio for 3C 454.3. ** 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 55540.186336 0.000709 0.59436 0.16614 0.94694 0 1.53405 0.26292 0.30235 0.05179 0.91178 0.20134 0.17944 0.03959 55540.187641 0.000596 0.48545 0.13236 0.94175 0 2.09805 0.32682 0.42811 0.06661 1.01850 0.22791 0.20653 0.04618 55540.188746 0.000509 0.63082 0.18238 0.92045 0 1.88443 0.33941 0.37638 0.06760 1.18873 0.26884 0.24597 0.05532 55540.189782 0.000527 0.69943 0.20794 0.97253 0 1.58162 0.30463 0.32479 0.06241 1.10623 0.25054 0.22388 0.05065 55540.190879 0.000570 0.72830 0.21706 0.94924 0 1.50772 0.29426 0.29197 0.05692 1.09808 0.24733 0.21309 0.04792 55540.191961 0.000512 0.78046 0.23611 0.92090 0 1.55105 0.30608 0.32017 0.06307 1.21053 0.27758 0.24042 0.05503 55540.192849 0.000376 1.90845 0.73948 0.95385 0 0.87080 0.27549 0.16977 0.05369 1.66187 0.37180 0.32312 0.07225 55540.193587 0.000362 0.86171 0.26703 0.99200 0 1.83983 0.39446 0.37482 0.08033 1.58540 0.35471 0.32312 0.07225 55540.194487 0.000538 0.90940 0.28396 0.95161 0 1.29926 0.28296 0.25113 0.05469 1.18154 0.26438 0.22637 0.05062 55540.195760 0.000735 0.66278 0.16892 0.96457 0 1.64674 0.26983 0.32812 0.05372 1.09143 0.21306 0.21809 0.04252
