/* ** ** 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 55848.111704 0.000799 0.90766 0.28460 0.98182 1 0.33560 0.07325 0.16154 0.03525 0.30461 0.06857 0.14722 0.03314 55848.113026 0.000523 2.12278 0.86100 0.97222 1 0.22103 0.07479 0.10758 0.03640 0.46919 0.10492 0.22857 0.05111 55848.114406 0.000857 0.82234 0.24704 0.91525 1 0.36712 0.07237 0.17845 0.03518 0.30190 0.06844 0.14630 0.03315 55848.115945 0.000683 1.19043 0.39934 1.00000 1 0.29357 0.07340 0.14222 0.03556 0.34947 0.07815 0.17021 0.03806 55848.117325 0.000697 0.88889 0.27559 0.93750 1 0.40991 0.08740 0.20000 0.04264 0.36436 0.08201 0.17667 0.03977 55848.118763 0.000741 0.67650 0.19664 0.98039 1 0.48650 0.09034 0.23674 0.04396 0.32912 0.07360 0.16000 0.03578 55848.120840 0.001336 0.89520 0.21411 0.95443 1 0.36235 0.06084 0.17654 0.02964 0.32437 0.05525 0.15830 0.02696
