/* ** ** 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 53948.054147 0.000431 0.10643 0.01336 0.98658 0 10.48961 0.40309 9.19783 0.35343 1.11637 0.13336 0.97815 0.11684 53948.054951 0.000373 0.10631 0.01399 1.00000 0 10.83492 0.44602 9.33595 0.38427 1.15189 0.14400 0.99390 0.12424 53948.055686 0.000362 0.08142 0.01209 0.98400 0 11.34394 0.45891 9.91903 0.40125 0.92359 0.13191 0.80771 0.11536 53948.056415 0.000367 0.08364 0.01255 0.99213 0 10.81294 0.44853 9.33163 0.38707 0.90441 0.13046 0.78199 0.11280 53948.057289 0.000506 0.08117 0.01070 0.98409 0 10.63261 0.38110 9.13936 0.32756 0.86307 0.10952 0.74187 0.09415 53948.058313 0.000508 0.12155 0.02811 1.00000 1 8.87498 0.68023 1.97469 0.15135 1.07875 0.23540 0.24000 0.05237 53948.059170 0.000349 0.17916 0.04262 1.00000 1 8.78322 0.83171 1.95338 0.18497 1.57362 0.34339 0.35000 0.07638 53948.060115 0.000596 0.12215 0.02913 0.90244 1 7.87660 0.60663 1.75339 0.13504 0.96209 0.21714 0.21438 0.04838 53948.061146 0.000436 0.12917 0.03130 1.00000 1 9.17026 0.75694 2.04108 0.16847 1.18452 0.26986 0.26212 0.05972 53948.062148 0.000566 0.11172 0.02632 0.94872 1 8.68110 0.64276 1.93483 0.14325 0.96984 0.21686 0.21622 0.04835 53948.063267 0.000552 0.11969 0.02887 0.97368 1 7.97927 0.63397 1.77565 0.14107 0.95502 0.21754 0.21253 0.04842 53948.064298 0.000479 0.12217 0.03000 0.93939 1 9.13838 0.73172 2.04034 0.16338 1.11645 0.25921 0.24927 0.05787 53948.065199 0.000421 0.13822 0.03306 1.00000 1 8.96881 0.76134 1.99969 0.16974 1.23966 0.27720 0.27586 0.06169 53948.066477 0.000857 0.06812 0.01602 0.94915 1 9.24542 0.53752 2.05942 0.11973 0.62981 0.14347 0.14042 0.03199 53948.067900 0.000566 0.11703 0.02792 0.97436 1 7.98947 0.61718 1.78901 0.13819 0.93501 0.21104 0.20873 0.04711 53948.068975 0.000508 0.14244 0.03333 1.00000 1 7.51507 0.63480 1.68557 0.14238 1.07041 0.23359 0.24000 0.05237 53948.070108 0.000625 0.10498 0.02463 0.93023 1 8.52855 0.60675 1.90434 0.13548 0.89536 0.20021 0.20000 0.04472 53948.071474 0.000741 0.09509 0.02189 0.94660 1 8.07492 0.54359 1.81606 0.12225 0.76783 0.16904 0.17259 0.03800
