/* ** ** 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 53674.474853 0.001046 0.62455 0.17509 1.00000 1 0.22961 0.04010 0.18536 0.03237 0.14340 0.03145 0.11612 0.02546 53674.476843 0.000915 0.40229 0.10662 0.96825 1 0.40345 0.05741 0.32594 0.04638 0.16230 0.03629 0.13115 0.02933 53674.478557 0.000799 1.00049 0.30952 0.98182 1 0.19254 0.04222 0.15483 0.03395 0.19264 0.04204 0.15556 0.03395 53674.480649 0.001293 0.77727 0.18436 0.99662 1 0.23049 0.03645 0.18455 0.02918 0.17915 0.03167 0.14431 0.02551 53674.523774 0.001874 0.37591 0.09664 0.99225 1 0.31892 0.04309 0.17600 0.02373 0.11989 0.02622 0.06563 0.01432 53674.527536 0.001888 0.36684 0.09613 0.97692 1 0.32219 0.04401 0.17217 0.02352 0.11819 0.02643 0.06299 0.01409 53674.530674 0.001249 0.87241 0.24141 0.97980 1 0.25512 0.04857 0.13563 0.02582 0.22257 0.04470 0.11821 0.02374
