/* ** ** 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 56276.528762 0.000512 0.91236 0.28527 0.92655 0 0.34942 0.07489 0.26417 0.05662 0.31879 0.07257 0.24025 0.05468 56276.529735 0.000460 0.79817 0.24307 0.93711 0 0.44013 0.08971 0.33241 0.06775 0.35130 0.07948 0.26593 0.06017 56276.530854 0.000660 0.67864 0.19859 0.96053 0 0.35388 0.06625 0.26815 0.05020 0.24016 0.05402 0.18194 0.04092 56276.532047 0.000532 0.63291 0.18310 0.95109 0 0.47214 0.08512 0.35770 0.06449 0.29882 0.06761 0.22642 0.05123 56276.533155 0.000576 0.54835 0.15387 0.96482 0 0.50245 0.08429 0.37725 0.06328 0.27552 0.06198 0.20753 0.04668 56276.534243 0.000512 0.72510 0.21567 0.95480 0 0.43412 0.08514 0.32759 0.06425 0.31478 0.07039 0.23708 0.05301 56276.535574 0.000819 0.35628 0.09370 0.97527 0 0.53787 0.07330 0.40700 0.05547 0.19163 0.04310 0.14437 0.03247 56276.536983 0.000590 0.56400 0.16174 0.96078 0 0.46859 0.08092 0.35429 0.06118 0.26428 0.06051 0.19990 0.04577 56276.538577 0.001004 0.69269 0.15198 0.95389 0 0.42057 0.05973 0.31317 0.04446 0.29133 0.04872 0.21722 0.03632
