/* ** ** 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 57678.647924 0.000420 0.13079 0.03112 0.97241 0 2.49719 0.20279 2.17315 0.17647 0.32661 0.07303 0.28416 0.06354 57678.648694 0.000350 0.17020 0.04116 0.96694 0 2.32412 0.21413 2.01141 0.18531 0.39557 0.08846 0.34245 0.07657 57678.649519 0.000475 0.13985 0.03343 0.98171 0 2.05758 0.17397 1.76898 0.14957 0.28776 0.06435 0.24886 0.05565 57678.650424 0.000431 0.12312 0.02957 0.95973 0 2.58911 0.20377 2.24247 0.17648 0.31876 0.07234 0.27652 0.06276 57678.651327 0.000472 0.13457 0.03204 0.96933 0 2.19644 0.17967 1.88423 0.15412 0.29558 0.06610 0.25359 0.05670 57678.652632 0.000833 0.10938 0.02103 0.97240 0 2.25657 0.13595 1.96199 0.11820 0.24683 0.04506 0.21460 0.03918
