/* ** ** 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 59665.955881 0.000408 0.08663 0.01311 0.98582 0 9.18918 0.38961 8.13754 0.34501 0.79609 0.11562 0.70563 0.10246 59665.956694 0.000405 0.08710 0.01272 0.97857 0 9.79521 0.40621 8.54948 0.35452 0.85319 0.11948 0.74577 0.10443 59665.957452 0.000353 0.10730 0.01600 1.00000 0 8.79901 0.41575 7.65808 0.36184 0.94414 0.13353 0.82104 0.11611 59665.958170 0.000365 0.09848 0.01481 0.99206 0 9.07274 0.41465 8.05340 0.36807 0.89346 0.12802 0.79300 0.11363 59665.959009 0.000475 0.07618 0.01132 0.97561 0 9.38060 0.37088 8.14937 0.32218 0.71457 0.10240 0.61953 0.08877 59665.959880 0.000396 0.08883 0.01362 0.97810 0 9.31888 0.40307 8.18488 0.35396 0.82777 0.12182 0.72419 0.10657 59665.960748 0.000472 0.08580 0.01265 0.96933 0 8.49521 0.35394 7.38810 0.30781 0.72886 0.10308 0.63397 0.08966 59665.961555 0.000336 0.10141 0.01506 0.98276 0 9.82610 0.44566 8.64465 0.39206 0.99642 0.14093 0.87866 0.12426 59665.962290 0.000399 0.09442 0.01399 0.97826 0 9.07468 0.40016 7.85901 0.34656 0.85681 0.12117 0.74198 0.10493 59665.963094 0.000405 0.08209 0.01239 0.99286 0 9.84901 0.40465 8.59560 0.35314 0.80855 0.11743 0.70563 0.10246 59665.963878 0.000379 0.09825 0.01442 0.97710 0 9.38272 0.41321 8.12429 0.35779 0.92184 0.12908 0.79820 0.11177 59665.964628 0.000370 0.09424 0.01395 0.97656 0 9.73077 0.42530 8.48846 0.37099 0.91702 0.12969 0.80133 0.11333 59665.965412 0.000414 0.08379 0.01265 0.98601 0 9.58187 0.39753 8.30678 0.34462 0.80282 0.11658 0.69563 0.10101 59665.966228 0.000402 0.12038 0.01637 0.97122 0 8.82191 0.38948 7.63822 0.33722 1.06195 0.13662 0.91946 0.11829
