/* ** ** 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 55890.795187 0.000494 0.96082 0.30079 0.97059 1 0.40323 0.08731 0.25648 0.05521 0.38744 0.08759 0.24122 0.05422 55890.796306 0.000625 0.83381 0.25032 1.00000 1 0.33969 0.07000 0.23220 0.04782 0.28324 0.06184 0.19535 0.04263 55890.797482 0.000552 0.85646 0.26057 0.94737 1 0.36797 0.07544 0.25838 0.05297 0.31515 0.07084 0.22112 0.04970 55890.798775 0.000741 0.53290 0.14820 1.00000 1 0.42003 0.06944 0.29441 0.04868 0.22383 0.05005 0.15686 0.03508 55890.800039 0.000523 0.65289 0.19117 0.97222 1 0.50232 0.09494 0.35000 0.06614 0.32796 0.07334 0.22857 0.05111 55890.801128 0.000566 1.06902 0.34956 1.00000 1 0.27553 0.06573 0.19244 0.04589 0.29454 0.06587 0.20513 0.04587 55890.802232 0.000537 1.11880 0.36912 1.00000 1 0.27888 0.06765 0.19429 0.04712 0.31201 0.06978 0.21622 0.04835 55890.803598 0.000828 0.78937 0.23905 0.98246 1 0.25857 0.05279 0.18113 0.03697 0.20411 0.04565 0.14286 0.03194 55890.805675 0.001249 0.74539 0.16409 0.99188 1 0.32865 0.04794 0.23210 0.03386 0.24497 0.04039 0.17304 0.02853
