/* ** ** 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 56231.640155 0.000552 0.54179 0.15057 1.00000 1 0.80687 0.13314 0.38814 0.06404 0.43716 0.09775 0.21053 0.04708 56231.641128 0.000421 1.08367 0.35864 0.96552 1 0.53450 0.12965 0.26154 0.06343 0.57922 0.13040 0.28390 0.06391 56231.642101 0.000552 0.68884 0.19960 1.00000 1 0.65142 0.12312 0.32000 0.06047 0.44872 0.09856 0.21971 0.04826 56231.643162 0.000508 0.72097 0.20737 0.97143 1 0.68760 0.12769 0.34118 0.06336 0.49574 0.10889 0.24556 0.05393 56231.644382 0.000712 0.52217 0.14721 0.97959 1 0.64038 0.10866 0.31703 0.05380 0.33438 0.07528 0.16561 0.03728 56231.645617 0.000523 0.67406 0.19854 0.97222 1 0.68411 0.12992 0.33785 0.06416 0.46113 0.10382 0.22712 0.05113 56231.646662 0.000523 0.48340 0.13030 0.99818 1 0.98001 0.15306 0.48235 0.07533 0.47374 0.10407 0.23234 0.05103
