/* ** ** 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 55398.787162 0.000336 0.18316 0.04585 0.98276 0 2.17949 0.21250 1.86629 0.18196 0.39920 0.09203 0.34211 0.07887 55398.787926 0.000428 0.12853 0.03056 0.99324 0 2.45913 0.19887 2.12229 0.17158 0.31607 0.07068 0.27256 0.06095 55398.788684 0.000330 0.17952 0.04175 0.97368 0 2.54496 0.23647 2.21185 0.20552 0.45686 0.09740 0.39706 0.08465 55398.789390 0.000376 0.14505 0.03520 0.96154 0 2.51666 0.21596 2.17901 0.18697 0.36505 0.08287 0.31627 0.07180 55398.790206 0.000440 0.15746 0.03145 0.96053 0 2.90117 0.21318 2.52596 0.18561 0.45682 0.08483 0.39792 0.07389 55398.791141 0.000495 0.10976 0.02585 0.97661 0 2.51352 0.18611 2.18592 0.16185 0.27588 0.06169 0.23992 0.05365 55398.791945 0.000310 0.15801 0.03857 0.97196 0 2.79096 0.25025 2.41169 0.21622 0.44100 0.10011 0.38013 0.08630 55398.792706 0.000451 0.10833 0.02549 0.97436 0 2.79443 0.20468 2.43506 0.17835 0.30273 0.06769 0.26360 0.05894 55398.793459 0.000301 0.17397 0.04221 0.99038 0 2.57212 0.24239 2.23775 0.21088 0.44746 0.10006 0.38900 0.08698 55398.794228 0.000469 0.11935 0.02901 0.93827 0 2.47100 0.19029 2.14863 0.16546 0.29493 0.06798 0.25658 0.05915 55398.795171 0.000475 0.11195 0.02641 0.98171 0 2.55397 0.19197 2.22319 0.16711 0.28592 0.06393 0.24886 0.05565 55398.795956 0.000310 0.16601 0.04131 0.97196 0 2.59881 0.24359 2.25885 0.21172 0.43143 0.09946 0.37500 0.08645 55398.796667 0.000402 0.18846 0.03970 0.97842 0 2.43896 0.20880 2.10986 0.18061 0.45964 0.08846 0.39772 0.07654 55398.797643 0.000573 0.10716 0.02526 0.97980 0 2.21548 0.16503 1.92816 0.14363 0.23741 0.05309 0.20653 0.04618 55398.798739 0.000524 0.16705 0.03145 0.98895 0 2.54305 0.18229 2.21155 0.15853 0.42482 0.07395 0.36933 0.06429
