/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55876.339798 0.000741 0.71792 0.21322 1.00000 1 0.46040 0.08997 0.21730 0.04246 0.33053 0.07393 0.15686 0.03508 55876.341411 0.000872 0.62650 0.18010 0.95000 1 0.48722 0.08793 0.22453 0.04050 0.30524 0.06830 0.14035 0.03138 55876.342660 0.000378 1.31013 0.45782 1.00000 1 0.50513 0.13501 0.23334 0.06236 0.66178 0.14898 0.30574 0.06883 55876.343633 0.000596 0.98737 0.31060 0.97561 1 0.45209 0.09995 0.20746 0.04586 0.44638 0.09989 0.20000 0.04472 55876.344868 0.000639 0.99137 0.31669 0.95455 1 0.40973 0.09224 0.18927 0.04261 0.40620 0.09206 0.18806 0.04263 55876.346596 0.001089 0.48155 0.13149 0.98667 1 0.47956 0.07514 0.22396 0.03509 0.23093 0.05164 0.10811 0.02417 55876.348441 0.000755 0.75961 0.22232 0.94231 1 0.47650 0.09217 0.22394 0.04331 0.36195 0.07950 0.17039 0.03742 55876.350286 0.001089 0.90599 0.22928 0.98812 1 0.39050 0.06962 0.18404 0.03281 0.35379 0.06354 0.16732 0.03005
