/* ** ** 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 56840.614928 0.000576 0.11812 0.02881 0.99497 0 2.06980 0.16638 1.67126 0.13433 0.24448 0.05631 0.19712 0.04540 56840.616039 0.000535 0.13464 0.03211 0.96757 0 2.03984 0.16919 1.65561 0.13732 0.27463 0.06141 0.22384 0.05005 56840.617193 0.000619 0.10998 0.02592 0.96262 0 2.17298 0.16167 1.76518 0.13134 0.23899 0.05344 0.19450 0.04349 56840.618267 0.000454 0.16689 0.04040 0.95541 0 1.97218 0.18276 1.60050 0.14825 0.32914 0.07360 0.26711 0.05973 56840.619138 0.000417 0.16264 0.03977 0.98611 0 2.12783 0.19406 1.72235 0.15706 0.34606 0.07852 0.27851 0.06320 56840.620075 0.000521 0.14202 0.03402 0.97222 0 1.97993 0.17027 1.61213 0.13863 0.28119 0.06288 0.22895 0.05120 56840.621418 0.000822 0.13500 0.02483 0.92638 0 2.34108 0.14627 1.90509 0.11903 0.31605 0.05467 0.25692 0.04444 56840.881605 0.000434 0.16510 0.04055 0.98000 0 1.93317 0.18166 1.62283 0.15250 0.31918 0.07242 0.26902 0.06105 56840.882907 0.000868 0.08975 0.02097 0.97333 0 1.81963 0.12351 1.52658 0.10361 0.16331 0.03652 0.13721 0.03068 56840.884785 0.001010 0.07102 0.01669 0.96848 0 1.96335 0.12019 1.64733 0.10084 0.13944 0.03164 0.11700 0.02655 56840.886628 0.000833 0.09705 0.02274 0.94792 0 1.79713 0.12560 1.51214 0.10568 0.17440 0.03900 0.14676 0.03282 56840.888159 0.000697 0.12647 0.02747 0.97095 0 1.93452 0.14374 1.62511 0.12074 0.24466 0.04994 0.20547 0.04194
