/* ** ** 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 56456.833764 0.000509 0.49542 0.13750 0.96591 0 0.63013 0.10244 0.46242 0.07507 0.31218 0.07022 0.23439 0.05272 56456.835040 0.000767 0.37116 0.09766 0.96981 0 0.55374 0.07679 0.42005 0.05825 0.20553 0.04596 0.15590 0.03486 56456.836516 0.000709 0.59921 0.17214 0.97959 0 0.36538 0.06530 0.27705 0.04952 0.21894 0.04924 0.16603 0.03734 56456.837717 0.000492 0.78817 0.23820 0.97059 0 0.40408 0.08157 0.30644 0.06186 0.31849 0.07163 0.24149 0.05431 56456.838701 0.000492 0.88958 0.27412 0.94118 0 0.36909 0.07774 0.27997 0.05897 0.32834 0.07385 0.24904 0.05601 56456.839777 0.000584 0.64880 0.18729 0.97525 0 0.41354 0.07550 0.31302 0.05715 0.26830 0.05999 0.20338 0.04548 56456.840975 0.000613 0.65982 0.19117 0.97170 0 0.38981 0.07117 0.29461 0.05379 0.25720 0.05786 0.19343 0.04350 56456.842158 0.000570 0.72519 0.21786 0.97970 0 0.37133 0.07282 0.28155 0.05522 0.26929 0.06128 0.20417 0.04646 56456.843920 0.001192 0.55657 0.11183 0.97087 0 0.46121 0.05568 0.34990 0.04224 0.25669 0.04123 0.19477 0.03128
