/* ** ** 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 55753.547339 0.001249 0.44597 0.12055 0.98837 1 0.29077 0.04412 0.20659 0.03122 0.12968 0.02901 0.09412 0.02105 55753.549648 0.001060 0.49135 0.13585 0.98630 1 0.31419 0.05058 0.22493 0.03621 0.15438 0.03470 0.11056 0.02485 55753.551725 0.001017 0.96487 0.30513 0.85728 1 0.19254 0.04305 0.13791 0.03084 0.18578 0.04154 0.13331 0.02981 55753.554485 0.001743 0.69519 0.15111 0.96355 1 0.25075 0.03499 0.17885 0.02495 0.17432 0.02905 0.12454 0.02076 55753.611908 0.001206 0.40279 0.10677 0.97590 1 0.30885 0.04396 0.24544 0.03493 0.12440 0.02782 0.09877 0.02208 55753.614043 0.000930 0.72101 0.21408 1.00000 1 0.21862 0.04240 0.17291 0.03354 0.15763 0.03544 0.12438 0.02796 55753.615990 0.001017 0.59285 0.16821 0.98571 1 0.24692 0.04312 0.19642 0.03430 0.14639 0.03273 0.11594 0.02593 55753.618212 0.001206 0.48368 0.13259 1.00000 1 0.24964 0.03958 0.19950 0.03163 0.12075 0.02700 0.09639 0.02155 55753.620304 0.000886 0.46898 0.12792 0.98361 1 0.35391 0.05528 0.28276 0.04416 0.16598 0.03711 0.13333 0.02981 55753.622047 0.000857 0.65074 0.18974 0.98440 1 0.26178 0.04861 0.21091 0.03917 0.17035 0.03829 0.13706 0.03081
