/* ** ** 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 54849.213974 0.066570 0.42964 0.08380 0.11421 1 0.09138 0.00976 0.06642 0.00709 0.03926 0.00641 0.02892 0.00471 54849.340784 0.006435 0.55990 0.11381 0.98087 1 0.07574 0.00918 0.06216 0.00754 0.04241 0.00692 0.03479 0.00568 54849.407463 0.006406 0.39997 0.08782 0.98532 1 0.08280 0.00970 0.06681 0.00783 0.03312 0.00615 0.02669 0.00496 54849.474804 0.006435 0.41198 0.08671 0.98989 1 0.09022 0.01030 0.07057 0.00806 0.03717 0.00657 0.02919 0.00516 54849.575133 0.040068 0.31213 0.07124 0.21781 1 0.07967 0.00923 0.05473 0.00610 0.02487 0.00489 0.01797 0.00346
