/* ** ** 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 55336.908028 0.000240 0.21961 0.01752 1.00000 0 23.61946 0.79072 21.74938 0.72811 5.18701 0.37559 4.77696 0.34587 55336.908520 0.000252 0.22138 0.01754 0.98851 0 22.68540 0.76118 20.89750 0.70117 5.02209 0.36042 4.62510 0.33190 55336.909061 0.000289 0.18976 0.01501 1.00000 0 22.70496 0.71423 20.80622 0.65447 4.30846 0.31278 3.94484 0.28637 55336.909602 0.000252 0.22192 0.01771 0.97701 0 22.83736 0.76849 20.91453 0.70374 5.06803 0.36676 4.63668 0.33553 55336.910105 0.000252 0.21797 0.01743 0.98851 0 22.86208 0.76656 21.02675 0.70503 4.98320 0.36170 4.58703 0.33299 55336.910588 0.000231 0.23102 0.01818 1.00000 0 23.72331 0.81419 21.93552 0.75284 5.48059 0.38808 5.06758 0.35884 55336.911083 0.000263 0.20452 0.01636 1.00000 0 22.96893 0.74998 21.23559 0.69339 4.69753 0.34315 4.34304 0.31725 55336.911630 0.000284 0.19539 0.01570 1.00000 0 21.99093 0.70684 20.32271 0.65322 4.29676 0.31640 3.97150 0.29246 55336.912165 0.000252 0.20596 0.01642 0.98851 0 24.24367 0.78773 22.27189 0.72364 4.99321 0.36364 4.59128 0.33435 55336.912672 0.000255 0.20788 0.01628 1.00000 0 23.61602 0.77348 21.80245 0.71408 4.90937 0.34915 4.53443 0.32249 55336.913193 0.000266 0.19756 0.01572 1.00000 0 23.53024 0.75557 21.58053 0.69291 4.64865 0.33845 4.26610 0.31051 55336.913696 0.000237 0.23988 0.01912 0.98780 0 22.54908 0.79374 20.46762 0.72037 5.40915 0.38688 4.90608 0.35094 55336.914174 0.000240 0.24311 0.01970 0.98795 0 21.74542 0.77191 19.81819 0.70343 5.28648 0.38507 4.81525 0.35066 55336.914668 0.000255 0.22071 0.01752 1.00000 0 22.49220 0.76334 20.46070 0.69438 4.96433 0.35616 4.51999 0.32436 55336.915169 0.000246 0.20140 0.01610 1.00000 0 25.31527 0.82318 22.94321 0.74597 5.09842 0.37235 4.62173 0.33746 55336.915655 0.000240 0.23854 0.01905 1.00000 0 22.32834 0.78752 20.31363 0.71633 5.32615 0.38151 4.84496 0.34699 55336.916127 0.000231 0.22404 0.01779 1.00000 0 24.66642 0.83808 22.19129 0.75397 5.52623 0.39658 4.97198 0.35679 55336.916633 0.000275 0.20597 0.01635 0.98947 0 22.36209 0.73015 20.33194 0.66388 4.60584 0.33337 4.19275 0.30340 55336.917163 0.000255 0.21717 0.01707 1.00000 0 23.20159 0.77357 20.98810 0.69971 5.03862 0.35864 4.56136 0.32462 55336.917692 0.000275 0.20169 0.01587 1.00000 0 23.08807 0.74595 20.75819 0.67069 4.65653 0.33416 4.18693 0.30046 55336.918216 0.000249 0.21017 0.01659 1.00000 0 24.32596 0.79818 22.13755 0.72631 5.11254 0.36712 4.65265 0.33407 55336.918742 0.000278 0.18446 0.01448 0.98958 0 24.98615 0.77033 22.73869 0.70100 4.60884 0.33283 4.19464 0.30292 55336.919292 0.000272 0.19947 0.01555 1.00000 0 23.41346 0.74872 21.28876 0.68074 4.67023 0.33216 4.24500 0.30190 55336.919807 0.000237 0.24536 0.01965 0.98780 0 21.93878 0.77702 20.14262 0.71340 5.38280 0.38657 4.93985 0.35470 55336.920421 0.000376 0.20878 0.01373 0.98462 0 23.73732 0.64178 21.54558 0.58245 4.95580 0.29699 4.49336 0.26927
