/* ** ** 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 56236.650135 0.000770 0.73581 0.21808 0.98113 1 0.44879 0.08725 0.20981 0.04078 0.33022 0.07387 0.15385 0.03440 56236.651733 0.000828 0.58019 0.16355 0.94737 1 0.54237 0.09205 0.25364 0.04304 0.31468 0.07083 0.14723 0.03314 56236.653171 0.000610 0.73088 0.21400 0.95238 1 0.57904 0.10944 0.27317 0.05162 0.42320 0.09464 0.20000 0.04472 56236.654522 0.000741 0.84409 0.25686 0.98039 1 0.40037 0.08263 0.19001 0.03922 0.33795 0.07557 0.16000 0.03578 56236.656149 0.000886 0.58932 0.16591 0.95082 1 0.48986 0.08377 0.23476 0.04014 0.28868 0.06456 0.13793 0.03084 56236.657848 0.000813 0.68169 0.19966 0.98214 1 0.44598 0.08358 0.21297 0.03991 0.30402 0.06843 0.14455 0.03254 56236.659882 0.001220 0.69094 0.14500 0.97703 1 0.57111 0.07633 0.27317 0.03650 0.39460 0.06384 0.18826 0.03046
