/* ** ** 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 55492.596916 0.000944 0.48371 0.13211 0.98462 1 0.31590 0.04900 0.25722 0.03989 0.15281 0.03435 0.12437 0.02796 55492.598500 0.000639 1.22088 0.40949 0.97727 1 0.18523 0.04631 0.15238 0.03810 0.22615 0.05057 0.18605 0.04160 55492.599894 0.000755 0.94960 0.29825 0.98077 1 0.20109 0.04410 0.16391 0.03595 0.19095 0.04293 0.15607 0.03508 55492.601405 0.000755 0.89272 0.27894 0.98077 1 0.21508 0.04694 0.17500 0.03819 0.19201 0.04294 0.15686 0.03508 55492.603293 0.001133 0.44612 0.12076 1.00000 1 0.27904 0.04207 0.22857 0.03446 0.12449 0.02799 0.10205 0.02294 55492.605007 0.000581 0.92473 0.29322 1.00000 1 0.26532 0.05965 0.21512 0.04836 0.24535 0.05487 0.20000 0.04472 55492.607302 0.001714 0.54984 0.11545 0.99959 1 0.26897 0.03400 0.22034 0.02785 0.14789 0.02480 0.12140 0.02035
