/* ** ** 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 58192.314382 0.000394 0.47643 0.08288 0.97059 0 1.86983 0.18498 1.57580 0.15585 0.89084 0.12748 0.75095 0.10746 58192.315187 0.000411 0.41591 0.07143 0.99296 0 2.01636 0.19142 1.68695 0.16015 0.83862 0.12001 0.70302 0.10060 58192.316066 0.000469 0.35386 0.05937 0.97531 0 2.10836 0.18169 1.76272 0.15192 0.74606 0.10740 0.62409 0.08984 58192.316963 0.000428 0.38028 0.06391 0.93919 0 2.23649 0.19707 1.87507 0.16521 0.85049 0.12170 0.71314 0.10205 58192.317724 0.000333 0.50954 0.08975 0.94783 0 2.13533 0.21672 1.78137 0.18078 1.08804 0.15663 0.90464 0.13022 58192.318506 0.000448 0.35816 0.05970 0.96129 0 2.23845 0.19445 1.87036 0.16248 0.80173 0.11406 0.66877 0.09514 58192.319261 0.000307 0.67326 0.12631 0.98113 0 1.69121 0.20179 1.39881 0.16689 1.13862 0.16486 0.94313 0.13658 58192.319944 0.000376 0.37267 0.06209 0.98462 0 2.52294 0.22221 2.10241 0.18516 0.94022 0.13298 0.78255 0.11067 58192.320641 0.000321 0.54555 0.09724 0.98198 0 2.01518 0.21645 1.67824 0.18027 1.09938 0.15639 0.91419 0.13005 58192.321324 0.000362 0.37601 0.06419 0.97600 0 2.55180 0.23069 2.13898 0.19337 0.95951 0.13895 0.80398 0.11643 58192.322070 0.000385 0.40513 0.06996 0.97744 0 2.22734 0.20948 1.85838 0.17476 0.90236 0.13069 0.75450 0.10926 58192.322826 0.000370 0.43717 0.07422 0.93750 0 2.30131 0.21533 1.92784 0.18039 1.00607 0.14252 0.84274 0.11938 58192.323526 0.000330 0.44861 0.07808 0.97368 0 2.37388 0.23222 1.97443 0.19313 1.06495 0.15329 0.88834 0.12788 58192.324217 0.000362 0.40248 0.06869 0.96800 0 2.46211 0.22586 2.02847 0.18608 0.99094 0.14262 0.81492 0.11731 58192.324941 0.000362 0.46755 0.08129 0.97600 0 2.12575 0.21248 1.74884 0.17480 0.99388 0.14139 0.81677 0.11619 58192.325670 0.000367 0.54878 0.08865 0.96850 0 2.18783 0.21186 1.79393 0.17370 1.20065 0.15523 0.98506 0.12735 58192.326344 0.000307 0.71994 0.13380 0.99057 0 1.65280 0.20152 1.36932 0.16695 1.18992 0.16690 0.98222 0.13776 58192.327201 0.000550 0.38374 0.05747 0.97895 0 2.16666 0.17434 1.79534 0.14445 0.83143 0.10502 0.68890 0.08702
