/* ** ** 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 56178.672268 0.000537 0.71836 0.20906 1.00000 1 0.41651 0.08017 0.31765 0.06113 0.29920 0.06531 0.22703 0.04954 56178.673401 0.000596 0.71574 0.21279 0.97561 1 0.35943 0.06944 0.27591 0.05330 0.25726 0.05813 0.19801 0.04474 56178.674926 0.000930 0.54310 0.15085 0.93750 1 0.31687 0.05169 0.24388 0.03978 0.17209 0.03868 0.13267 0.02982 56178.676291 0.000436 0.95720 0.30429 1.00000 1 0.35705 0.07984 0.27586 0.06169 0.34177 0.07722 0.26402 0.05966 56178.677177 0.000450 1.03469 0.32720 0.93548 1 0.34524 0.07720 0.26667 0.05963 0.35722 0.07988 0.27586 0.06169 56178.678194 0.000566 0.62720 0.17775 0.97436 1 0.45517 0.08230 0.35202 0.06365 0.28548 0.06230 0.22105 0.04824 56178.679080 0.000320 1.22721 0.42857 1.00000 1 0.38151 0.10196 0.29474 0.07877 0.46820 0.10524 0.36183 0.08133 56178.680068 0.000668 0.74387 0.22381 1.00000 1 0.30090 0.06018 0.23256 0.04651 0.22383 0.05031 0.17305 0.03890 56178.681244 0.000508 0.85447 0.25944 0.94286 1 0.36534 0.07458 0.28236 0.05764 0.31217 0.07017 0.24122 0.05422 56178.682465 0.000712 0.69454 0.19607 0.97094 1 0.34271 0.06301 0.26490 0.04870 0.23802 0.05099 0.18413 0.03944
