/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 57633.323566 0.000885 0.12448 0.03004 0.97386 0 1.25372 0.10215 1.06481 0.08675 0.15606 0.03545 0.13261 0.03012 57633.325525 0.001073 0.10308 0.02421 0.97305 0 1.25881 0.09031 1.07475 0.07711 0.12975 0.02901 0.11099 0.02482 57633.327414 0.000816 0.16455 0.03989 0.96807 0 1.04358 0.09772 0.89194 0.08352 0.17172 0.03840 0.14677 0.03282 57633.328821 0.000590 0.16412 0.03959 0.95588 0 1.46492 0.13255 1.25260 0.11334 0.24042 0.05376 0.20547 0.04594 57633.330160 0.000749 0.13882 0.03374 0.98070 0 1.31685 0.11400 1.12508 0.09740 0.18281 0.04152 0.15558 0.03534 57633.331503 0.000593 0.17849 0.04231 0.95610 0 1.41163 0.13060 1.20453 0.11143 0.25196 0.05498 0.21464 0.04684 57633.333019 0.000923 0.12456 0.02957 0.97179 0 1.22299 0.09752 1.03985 0.08292 0.15233 0.03406 0.12925 0.02890
