/* ** ** 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 57479.598393 0.000738 0.10978 0.02592 0.97647 0 1.77394 0.13437 1.45623 0.11024 0.19474 0.04355 0.16091 0.03598 57479.599623 0.000492 0.14171 0.03540 0.98235 0 1.95284 0.17070 1.62662 0.14218 0.27673 0.06475 0.23047 0.05392 57479.600754 0.000639 0.11764 0.02786 0.95023 0 1.95155 0.15202 1.62301 0.12643 0.22958 0.05133 0.19079 0.04266 57479.602033 0.000639 0.12457 0.02961 0.96833 0 1.81252 0.14592 1.50392 0.12108 0.22579 0.05049 0.18723 0.04187 57479.603193 0.000521 0.16579 0.04063 0.93889 0 1.70144 0.15710 1.41292 0.13046 0.28208 0.06404 0.23397 0.05310 57479.604154 0.000440 0.16738 0.04049 0.96053 0 1.97193 0.18187 1.63935 0.15119 0.33006 0.07380 0.27443 0.06136 57479.605161 0.000567 0.12058 0.02943 0.99490 0 1.99505 0.16074 1.65900 0.13367 0.24057 0.05543 0.20007 0.04610 57479.606321 0.000593 0.11115 0.02624 0.98537 0 2.14632 0.16233 1.78444 0.13496 0.23857 0.05335 0.19835 0.04435 57479.607594 0.000680 0.10885 0.02568 0.96170 0 1.95670 0.14699 1.62824 0.12231 0.21299 0.04763 0.17729 0.03964 57479.608864 0.000590 0.12896 0.03112 0.97059 0 1.86145 0.15268 1.54845 0.12701 0.24005 0.05449 0.19970 0.04533 57479.610635 0.001181 0.09796 0.01821 0.97953 0 1.99986 0.11198 1.65989 0.09295 0.19590 0.03473 0.16279 0.02886 57479.666051 0.000891 0.11351 0.02787 0.97727 0 1.97224 0.15721 1.12456 0.08751 0.22387 0.05200 0.13141 0.02981 57479.668016 0.001073 0.08786 0.02053 0.97574 0 1.94195 0.13139 1.24604 0.08428 0.17062 0.03816 0.11068 0.02475 57479.670996 0.001907 0.08473 0.01542 0.98331 0 1.88704 0.09723 1.22103 0.06291 0.15990 0.02790 0.10353 0.01806
