/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56370.067039 0.000333 0.15834 0.01219 1.00000 0 24.76792 0.70269 22.00356 0.62420 3.92181 0.28071 3.48885 0.24971 56370.067664 0.000292 0.16371 0.01275 1.00000 0 26.89008 0.78620 23.88356 0.69822 4.40220 0.31766 3.91294 0.28224 56370.068300 0.000344 0.14773 0.01121 0.99160 0 25.72719 0.70349 23.11104 0.63195 3.80055 0.26916 3.41401 0.24179 56370.068971 0.000327 0.15636 0.01194 0.98230 0 25.70768 0.72165 23.09541 0.64832 4.01970 0.28540 3.61126 0.25640 56370.069596 0.000298 0.16020 0.01264 0.99029 0 26.81932 0.77649 23.97059 0.69390 4.29656 0.31530 3.84069 0.28186 56370.070169 0.000275 0.18186 0.01422 1.00000 0 25.58201 0.78447 22.99198 0.70505 4.65223 0.33471 4.18116 0.30081 56370.070734 0.000289 0.17064 0.01326 1.00000 0 26.17150 0.77888 23.35956 0.69523 4.46602 0.32050 3.99214 0.28647 56370.071283 0.000260 0.19146 0.01514 1.00000 0 25.53323 0.80986 22.94546 0.72778 4.88866 0.35404 4.39323 0.31816 56370.071804 0.000260 0.18002 0.01419 1.00000 0 27.04107 0.82985 24.28572 0.74528 4.86806 0.35347 4.37097 0.31738 56370.072360 0.000295 0.16477 0.01299 1.00000 0 26.07177 0.76765 23.28825 0.68564 4.29575 0.31404 3.83890 0.28061 56370.072918 0.000263 0.18263 0.01436 0.98901 0 26.76845 0.81947 24.05632 0.73644 4.88861 0.35404 4.39323 0.31816 56370.073474 0.000292 0.16614 0.01292 1.00000 0 26.34241 0.77637 23.67237 0.69768 4.37641 0.31485 3.93278 0.28294 56370.074052 0.000286 0.16814 0.01328 1.00000 0 26.32515 0.78137 23.65550 0.70213 4.42626 0.32397 3.97731 0.29111 56370.074622 0.000284 0.15697 0.01219 1.00000 0 28.59392 0.82251 25.69065 0.73900 4.48849 0.32375 4.03273 0.29088 56370.075143 0.000237 0.19426 0.01528 0.98780 0 28.09353 0.89270 25.24320 0.80213 5.45750 0.39263 4.90383 0.35280 56370.075658 0.000278 0.17569 0.01362 1.00000 0 26.32441 0.79197 23.65866 0.71177 4.62491 0.33054 4.15657 0.29707 56370.076272 0.000336 0.14051 0.01095 0.98276 0 27.20952 0.73748 24.44572 0.66257 3.82310 0.27946 3.43480 0.25107 56370.076885 0.000278 0.17739 0.01381 1.00000 0 25.94712 0.79127 23.31561 0.71102 4.60264 0.32979 4.13570 0.29633 56370.077704 0.000541 0.17136 0.00955 0.98930 0 27.48827 0.57900 24.69817 0.52023 4.71032 0.24297 4.23217 0.21831
