/* ** ** Swift/XRT hardness ratio for PKS 1156-221. ** 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 55881.339342 0.337018 0.77683 0.24261 0.03290 1 0.02276 0.00454 0.01411 0.00272 0.01768 0.00425 0.00996 0.00228 56152.808765 0.041192 0.85696 0.26834 0.37102 1 0.01722 0.00374 0.00844 0.00180 0.01475 0.00332 0.00760 0.00170 58907.878409 0.036465 0.52478 0.05967 0.47213 1 0.09586 0.00641 0.07648 0.00511 0.05031 0.00463 0.04004 0.00368 58910.866624 0.036297 0.50292 0.15033 0.47221 1 0.03479 0.00591 0.01471 0.00224 0.01750 0.00430 0.00678 0.00152 59016.281973 0.009674 0.54252 0.08947 0.99358 1 0.07991 0.00785 0.06370 0.00626 0.04335 0.00574 0.03446 0.00456
