/* ** ** 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 57928.770889 0.003079 0.59582 0.16834 0.97170 1 0.13843 0.02388 0.06540 0.01127 0.08248 0.01846 0.03884 0.00868 57928.776859 0.002891 0.88805 0.27486 0.97990 1 0.09943 0.02128 0.04640 0.00993 0.08830 0.01975 0.04103 0.00917 57928.808084 0.028334 0.86731 0.26521 0.04386 1 0.13566 0.02829 0.10824 0.02257 0.11766 0.02631 0.09351 0.02091 57928.837973 0.001554 0.69715 0.20474 0.99065 1 0.13505 0.02552 0.10769 0.02035 0.09415 0.02116 0.07509 0.01688 57928.841284 0.001758 0.94141 0.23016 0.98427 1 0.14722 0.02519 0.11728 0.02007 0.13860 0.02420 0.11050 0.01930
