/* ** ** 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 58515.205600 0.000336 0.19506 0.01527 0.98276 0 20.01193 0.63076 17.84906 0.56256 3.90351 0.27974 3.48282 0.24954 58515.206248 0.000312 0.18771 0.01451 1.00000 0 21.82329 0.67745 19.87105 0.61685 4.09647 0.29011 3.73019 0.26417 58515.206885 0.000324 0.19263 0.01509 1.00000 0 20.41811 0.64974 18.59806 0.59182 3.93318 0.28148 3.58249 0.25639 58515.207521 0.000312 0.19887 0.01570 1.00000 0 20.19533 0.64924 18.40176 0.59158 4.01617 0.28965 3.65952 0.26393 58515.208187 0.000353 0.16583 0.01314 0.99180 0 21.32716 0.62899 19.42624 0.57293 3.53661 0.26019 3.22141 0.23700 58515.208884 0.000344 0.17719 0.01396 1.00000 0 20.48296 0.62796 18.65814 0.57201 3.62929 0.26349 3.30602 0.24002 58515.209596 0.000367 0.16518 0.01278 0.99213 0 20.93896 0.61270 19.07632 0.55819 3.45872 0.24781 3.15112 0.22577 58515.210296 0.000333 0.18628 0.01462 0.98261 0 20.61457 0.63825 18.77558 0.58132 3.84013 0.27696 3.49760 0.25226 58515.210962 0.000333 0.17558 0.01373 1.00000 0 21.49243 0.64845 19.57391 0.59056 3.77361 0.27216 3.43677 0.24787 58515.211665 0.000370 0.16650 0.01331 1.00000 0 20.18070 0.60092 18.29514 0.54474 3.36002 0.24929 3.04822 0.22602 58515.212622 0.000587 0.17563 0.01037 0.99891 0 21.66295 0.48987 19.73575 0.44629 3.80474 0.20756 3.46627 0.18910 58515.272771 0.000336 0.18518 0.01459 0.99138 0 19.99675 0.61856 18.47813 0.57159 3.70304 0.26829 3.42191 0.24792 58515.273500 0.000394 0.14586 0.01125 0.99265 0 22.00140 0.60204 20.00164 0.54727 3.20905 0.23137 2.92555 0.21093 58515.274223 0.000330 0.18585 0.01435 0.98246 0 20.92234 0.64044 19.26363 0.58963 3.88842 0.27560 3.58250 0.25391 58515.274851 0.000298 0.21188 0.01678 1.00000 0 19.81119 0.65739 18.16770 0.60285 4.19764 0.30187 3.85391 0.27714 58515.275754 0.000605 0.18809 0.01065 0.99043 0 21.24836 0.47576 19.58228 0.43844 3.99667 0.20783 3.68322 0.19151
