/* ** ** 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 55541.045662 0.000857 0.93671 0.29343 0.96610 1 0.18500 0.04058 0.14929 0.03274 0.17329 0.03876 0.14035 0.03138 55541.047158 0.000639 0.89925 0.27910 1.00000 1 0.24921 0.05364 0.20280 0.04365 0.22410 0.05011 0.18182 0.04066 55541.048567 0.000770 0.66658 0.19405 0.98113 1 0.28833 0.05374 0.23121 0.04309 0.19219 0.04298 0.15385 0.03440 55541.050427 0.001089 0.54983 0.15482 0.98667 1 0.24420 0.04179 0.19773 0.03383 0.13427 0.03003 0.10811 0.02417 55541.052736 0.001220 0.45418 0.12370 1.00000 1 0.26313 0.04091 0.21115 0.03283 0.11951 0.02673 0.09524 0.02130 55541.054755 0.000799 0.58035 0.16467 0.98182 1 0.31703 0.05488 0.25435 0.04403 0.18399 0.04136 0.14741 0.03314 55541.056411 0.000857 0.64518 0.18626 1.00000 1 0.25978 0.04743 0.21053 0.03844 0.16761 0.03748 0.13559 0.03032 55541.058125 0.000857 0.68772 0.18572 0.99742 1 0.29633 0.05239 0.23704 0.04190 0.20379 0.04160 0.16313 0.03330
