/* ** ** 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 56551.752849 0.000830 0.43998 0.11886 0.97909 0 0.43764 0.06634 0.32247 0.04887 0.19255 0.04306 0.14259 0.03188 56551.754999 0.001319 0.53057 0.14757 0.98026 0 0.22580 0.03735 0.16863 0.02789 0.11980 0.02679 0.08963 0.02004 56551.757337 0.001019 0.40706 0.10927 0.95170 0 0.38846 0.05615 0.29066 0.04201 0.15813 0.03577 0.11831 0.02676 56551.758960 0.000605 1.00574 0.32410 0.98086 0 0.25882 0.05974 0.19309 0.04457 0.26031 0.05854 0.19439 0.04372 56551.760358 0.000793 0.93938 0.29795 0.97445 0 0.21425 0.04819 0.16004 0.03599 0.20126 0.04501 0.15006 0.03356 56551.761680 0.000530 1.16983 0.38591 0.97268 0 0.25711 0.06236 0.19241 0.04667 0.30078 0.06726 0.22509 0.05033 56551.762951 0.000741 0.67683 0.19839 0.96094 0 0.31955 0.05957 0.23819 0.04441 0.21628 0.04892 0.16111 0.03644
