/* ** ** Swift/XRT hardness ratio for PKS 1830-21. ** 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 55489.584405 0.001118 2.87228 1.26147 0.96104 1 0.04728 0.01787 0.03733 0.01411 0.13581 0.03037 0.10811 0.02417 55489.586802 0.001278 1.96311 0.76034 0.98864 1 0.05860 0.01853 0.04651 0.01471 0.11504 0.02572 0.09195 0.02056 55489.589155 0.001075 3.60747 1.80386 1.00000 1 0.03786 0.01693 0.02985 0.01335 0.13658 0.03054 0.10811 0.02417 55489.592336 0.002106 2.50765 0.79802 0.99026 1 0.05340 0.01460 0.04182 0.01144 0.13390 0.02178 0.10558 0.01717 55489.651177 0.001583 1.68569 0.56696 0.98387 1 0.06907 0.01846 0.05283 0.01412 0.11643 0.02377 0.08952 0.01827
