/* ** ** 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 53675.263524 0.001729 0.44478 0.09492 0.98212 1 0.30457 0.03615 0.24510 0.02909 0.13547 0.02402 0.10919 0.01936 53675.329380 0.000842 0.58250 0.16826 0.98276 1 0.33890 0.06092 0.23396 0.04202 0.19741 0.04464 0.13898 0.03140 53675.331240 0.000988 0.49414 0.13479 0.97059 1 0.34304 0.05358 0.24477 0.03823 0.16951 0.03791 0.12121 0.02710 53675.332779 0.000552 0.86846 0.26269 0.99533 1 0.35687 0.07475 0.25573 0.05356 0.30993 0.06763 0.22209 0.04846 53675.395852 0.000697 0.76776 0.23141 1.00000 1 0.27119 0.05446 0.21654 0.04349 0.20821 0.04680 0.16585 0.03728 53675.398264 0.001714 0.40981 0.08597 0.96723 1 0.34272 0.03871 0.27376 0.03092 0.14045 0.02483 0.11215 0.01983
