/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 57244.437512 0.001045 0.07621 0.01769 0.98338 0 1.72126 0.10753 1.48722 0.09289 0.13118 0.02933 0.11286 0.02524 57244.439289 0.000732 0.12463 0.02961 0.98814 0 1.48852 0.11957 1.28642 0.10332 0.18551 0.04148 0.16027 0.03584 57244.440643 0.000622 0.13038 0.03195 0.97674 0 1.64703 0.13740 1.42594 0.11896 0.21473 0.04948 0.18576 0.04281 57244.442081 0.000810 0.10438 0.02492 0.97500 0 1.59717 0.11817 1.38759 0.10266 0.16671 0.03784 0.14483 0.03287 57244.443676 0.000784 0.10958 0.02584 0.97786 0 1.59168 0.11909 1.37592 0.10295 0.17442 0.03900 0.15120 0.03381 57244.445426 0.000966 0.09941 0.02368 0.96407 0 1.44737 0.10467 1.23894 0.08961 0.14389 0.03265 0.12279 0.02787 57244.447006 0.000613 0.14454 0.03466 0.98585 0 1.54570 0.13397 1.32612 0.11494 0.22341 0.04996 0.19171 0.04287 57244.448508 0.000883 0.10360 0.02437 0.99016 0 1.49154 0.10888 1.28582 0.09386 0.15453 0.03456 0.13267 0.02967 57244.451780 0.002390 0.05745 0.01057 0.97337 0 1.63359 0.07023 1.39941 0.06016 0.09385 0.01679 0.08026 0.01436
