/* ** ** 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 56442.038762 0.000350 0.31876 0.05166 0.95041 0 3.18828 0.25232 2.73794 0.21665 1.01629 0.14373 0.87102 0.12318 56442.039827 0.000715 0.33332 0.03576 0.98381 0 3.41027 0.18244 2.92892 0.15669 1.13672 0.10569 0.97806 0.09092 56442.040883 0.000341 0.38646 0.06509 0.95763 0 2.62040 0.23263 2.26977 0.20150 1.01269 0.14494 0.87712 0.12553 56442.041876 0.000651 0.37642 0.04280 0.96444 0 3.04221 0.18164 2.63504 0.15733 1.14516 0.11080 0.99220 0.09600 56442.042943 0.000417 0.27443 0.04364 0.95833 0 3.09990 0.22892 2.68426 0.19823 0.85070 0.11982 0.73655 0.10374 56442.043710 0.000350 0.30151 0.04876 0.97521 0 3.25328 0.25524 2.81535 0.22088 0.98090 0.13872 0.84887 0.12005 56442.044451 0.000391 0.25180 0.04056 0.98519 0 3.45688 0.24776 2.97692 0.21335 0.87045 0.12556 0.74841 0.10793 56442.045154 0.000312 0.35337 0.05900 0.99074 0 3.06246 0.26313 2.62196 0.22528 1.08218 0.15493 0.92630 0.13257 56442.045967 0.000501 0.37122 0.04795 0.97688 0 3.07776 0.20702 2.65545 0.17861 1.14252 0.12599 0.98640 0.10878 56442.047613 0.001146 0.36300 0.03105 0.96717 0 3.16965 0.13989 2.72204 0.12014 1.15060 0.08431 0.98806 0.07239 56442.049364 0.000605 0.29051 0.03539 0.99043 0 3.38276 0.19724 2.92252 0.17040 0.98272 0.10511 0.84912 0.09082
