/* ** ** 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 58139.577328 0.000370 0.39227 0.06637 0.99219 0 2.30291 0.20756 1.99022 0.17934 0.90336 0.12935 0.78011 0.11171 58139.578110 0.000411 0.32783 0.05345 0.96479 0 2.57638 0.20904 2.23032 0.18095 0.84462 0.11945 0.73114 0.10340 58139.578903 0.000382 0.39855 0.06709 0.99242 0 2.26995 0.20726 1.91872 0.17521 0.90470 0.12795 0.76463 0.10814 58139.579672 0.000388 0.40171 0.06842 0.97015 0 2.23419 0.20285 1.88654 0.17128 0.89749 0.12934 0.75790 0.10921 58139.580471 0.000411 0.42507 0.07273 0.95775 0 2.02889 0.19265 1.72000 0.16331 0.86242 0.12275 0.73250 0.10424 58139.581267 0.000385 0.44410 0.07576 0.98496 0 2.02725 0.19337 1.72034 0.16408 0.90031 0.12733 0.76463 0.10814 58139.582057 0.000405 0.39457 0.06601 0.98571 0 2.16389 0.19333 1.83561 0.16398 0.85380 0.12076 0.72585 0.10265 58139.582855 0.000394 0.40594 0.06990 1.00000 0 2.10979 0.19496 1.79361 0.16571 0.85645 0.12444 0.72713 0.10566 58139.583645 0.000396 0.38258 0.06440 0.98540 0 2.26678 0.20379 1.92825 0.17337 0.86723 0.12343 0.73793 0.10501 58139.584447 0.000405 0.37725 0.06323 0.98571 0 2.26826 0.19965 1.92755 0.16965 0.85570 0.12207 0.72848 0.10390 58139.585158 0.000307 0.60509 0.10718 0.99057 0 1.90439 0.20985 1.64089 0.18079 1.15232 0.15980 0.99213 0.13758 58139.585885 0.000420 0.33755 0.05548 0.99310 0 2.38919 0.20001 2.06144 0.17257 0.80648 0.11406 0.69560 0.09837 58139.586758 0.000454 0.40921 0.06924 0.94904 0 1.89482 0.17347 1.63183 0.14941 0.77538 0.11034 0.66859 0.09514 58139.587583 0.000370 0.42513 0.07176 0.98438 0 2.19949 0.20444 1.89672 0.17629 0.93508 0.13174 0.80654 0.11363 58139.588411 0.000457 0.33554 0.05350 0.96835 0 2.38451 0.18977 2.05784 0.16378 0.80009 0.11055 0.69039 0.09539
