/* ** ** 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 57872.205490 0.000249 0.20754 0.01644 1.00000 0 25.84668 0.84706 22.13047 0.72515 5.36434 0.38692 4.59555 0.33146 57872.205956 0.000217 0.24583 0.01969 1.00000 0 25.99104 0.93091 21.51797 0.77068 6.38927 0.45781 5.29379 0.37930 57872.206419 0.000246 0.21264 0.01682 1.00000 0 25.82943 0.85970 22.09168 0.73528 5.49227 0.39414 4.69676 0.33701 57872.206936 0.000272 0.19546 0.01561 1.00000 0 25.01379 0.79923 21.43007 0.68473 4.88930 0.35782 4.18909 0.30658 57872.207452 0.000243 0.20964 0.01656 1.00000 0 26.45920 0.87437 22.67162 0.74921 5.54694 0.39801 4.75267 0.34102 57872.207943 0.000249 0.20924 0.01690 1.00000 0 25.26942 0.84213 21.66020 0.72185 5.28730 0.38902 4.53219 0.33347 57872.208458 0.000266 0.19221 0.01532 1.00000 0 25.82518 0.82122 22.14528 0.70420 4.96383 0.36281 4.25636 0.31110 57872.208988 0.000263 0.20245 0.01593 1.00000 0 25.16694 0.81814 21.55172 0.70062 5.09496 0.36506 4.36301 0.31261 57872.209526 0.000275 0.17894 0.01427 1.00000 0 26.77480 0.82219 22.92837 0.70407 4.79100 0.35252 4.10282 0.30188 57872.210050 0.000249 0.21381 0.01699 0.98837 0 25.50315 0.84498 21.87012 0.72461 5.45275 0.39383 4.67539 0.33769 57872.210545 0.000246 0.21558 0.01696 1.00000 0 25.50253 0.84740 21.88531 0.72721 5.49783 0.39192 4.71813 0.33633 57872.211063 0.000272 0.18053 0.01432 1.00000 0 26.91984 0.83108 23.07525 0.71239 4.85972 0.35520 4.16579 0.30448 57872.211612 0.000278 0.17878 0.01410 1.00000 0 26.93055 0.82163 23.04945 0.70322 4.81451 0.35003 4.12074 0.29959 57872.212188 0.000298 0.17412 0.01348 0.99029 0 26.22945 0.78081 22.46563 0.66876 4.56707 0.32640 3.91213 0.27959 57872.212770 0.000284 0.19168 0.01532 0.97959 0 24.99089 0.78714 21.40854 0.67430 4.79029 0.35195 4.10377 0.30151 57872.213360 0.000307 0.17602 0.01368 0.98113 0 25.46202 0.75936 21.80823 0.65039 4.48171 0.32158 3.83870 0.27544 57872.213919 0.000252 0.21125 0.01669 1.00000 0 25.23135 0.84003 21.60339 0.71925 5.33007 0.38190 4.56361 0.32698 57872.214465 0.000295 0.17935 0.01389 0.99020 0 25.84367 0.78072 22.13823 0.66879 4.63499 0.33041 3.97070 0.28305 57872.215247 0.000486 0.18693 0.01114 0.99405 0 25.90814 0.61172 22.18158 0.52374 4.84292 0.26501 4.14646 0.22690
