/* ** ** Swift/XRT hardness ratio for QSO B0917+449. ** 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 54849.381303 0.233899 0.41214 0.03876 0.15102 1 0.08442 0.00434 0.06385 0.00324 0.03479 0.00274 0.02691 0.00211 55133.634746 0.102036 0.44155 0.10077 0.11097 1 0.06273 0.00786 0.03745 0.00438 0.02770 0.00528 0.01589 0.00286 55133.663058 0.014148 0.51243 0.08244 0.99281 1 0.06004 0.00566 0.04758 0.00449 0.03077 0.00401 0.02437 0.00318 55873.369675 0.346976 0.40694 0.08297 0.06111 1 0.03173 0.00349 0.02281 0.00251 0.01291 0.00222 0.00931 0.00160 58259.290681 0.038439 0.51999 0.09620 0.29038 1 0.05545 0.00607 0.04490 0.00492 0.02884 0.00430 0.02342 0.00349
