/* ** ** 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 56435.364919 0.000373 0.34671 0.05727 0.97674 0 2.65641 0.22321 2.28143 0.19171 0.92100 0.13099 0.79098 0.11250 56435.365663 0.000370 0.33460 0.05476 0.97656 0 2.78365 0.22935 2.39504 0.19733 0.93140 0.13172 0.80133 0.11333 56435.366447 0.000414 0.30522 0.04951 1.00000 0 2.66658 0.21194 2.29512 0.18241 0.81390 0.11510 0.70047 0.09906 56435.367202 0.000341 0.41261 0.07071 0.98305 0 2.39606 0.22313 2.06087 0.19192 0.98864 0.14222 0.85048 0.12235 56435.367868 0.000324 0.41874 0.07098 0.95536 0 2.57374 0.23410 2.21272 0.20126 1.07772 0.15416 0.92672 0.13256 56435.368568 0.000376 0.31945 0.05219 0.97692 0 2.86724 0.23040 2.45285 0.19710 0.91595 0.13027 0.78475 0.11161 56435.369320 0.000376 0.34919 0.05791 0.99231 0 2.59274 0.22119 2.20765 0.18831 0.90536 0.12877 0.77258 0.10988 56435.370032 0.000336 0.39917 0.06764 0.99138 0 2.52870 0.22972 2.15697 0.19594 1.00938 0.14439 0.86225 0.12334 56435.370880 0.000512 0.28120 0.04570 0.96610 0 2.38966 0.18073 2.05208 0.15519 0.67198 0.09667 0.57693 0.08300 56435.371728 0.000336 0.42874 0.07257 0.97414 0 2.44283 0.22718 2.06468 0.19201 1.04735 0.14812 0.88643 0.12536 56435.372419 0.000356 0.39685 0.06684 0.98374 0 2.43083 0.21930 2.07904 0.18756 0.96467 0.13720 0.82366 0.11715 56435.373117 0.000341 0.53407 0.08837 0.97458 0 2.17522 0.21372 1.85380 0.18210 1.16171 0.15467 0.98858 0.13159 56435.373820 0.000362 0.50298 0.07961 0.98400 0 2.29953 0.21206 1.96213 0.18091 1.15661 0.14878 0.98943 0.12727 56435.374508 0.000327 0.40452 0.06812 0.97345 0 2.63856 0.23786 2.24015 0.20193 1.06736 0.15181 0.90603 0.12886 56435.375614 0.000778 0.35058 0.04157 0.96283 0 2.48401 0.14985 2.11937 0.12785 0.87084 0.08889 0.74255 0.07579
