/* ** ** 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 55326.887100 0.000269 0.16876 0.01288 1.00000 0 27.69905 0.80770 25.65556 0.74811 4.67457 0.32972 4.32979 0.30540 55326.887641 0.000272 0.16541 0.01287 1.00000 0 27.63329 0.80982 25.44253 0.74556 4.57084 0.32948 4.20556 0.30318 55326.888171 0.000258 0.16780 0.01306 0.98876 0 28.90183 0.84875 26.77431 0.78627 4.84967 0.34961 4.49231 0.32385 55326.888720 0.000292 0.15250 0.01198 0.99010 0 27.89942 0.78273 25.84963 0.72522 4.25467 0.31224 3.94208 0.28930 55326.889270 0.000258 0.16390 0.01264 1.00000 0 29.53086 0.85656 27.36115 0.79363 4.83997 0.34578 4.48436 0.32038 55326.889782 0.000255 0.17521 0.01374 0.98864 0 28.16385 0.84343 26.09445 0.78145 4.93466 0.35753 4.57207 0.33126 55326.890323 0.000286 0.16137 0.01229 0.98990 0 27.82402 0.79402 25.60717 0.73075 4.48986 0.31712 4.13159 0.29182 55326.890865 0.000255 0.18255 0.01416 1.00000 0 27.02488 0.83264 24.86376 0.76602 4.93343 0.35109 4.53279 0.32258 55326.891362 0.000243 0.18957 0.01492 1.00000 0 26.94519 0.84595 24.96517 0.78378 5.10808 0.36870 4.73272 0.34160 55326.891869 0.000263 0.16314 0.01298 0.98901 0 28.53543 0.83729 26.43897 0.77578 4.65533 0.34442 4.31331 0.31912 55326.892407 0.000275 0.16806 0.01293 0.98947 0 27.25256 0.79567 25.25003 0.73721 4.58001 0.32594 4.24346 0.30199 55326.892988 0.000307 0.14324 0.01098 1.00000 0 28.22773 0.76986 26.15351 0.71329 4.04338 0.28961 3.74627 0.26833 55326.893553 0.000258 0.17401 0.01350 0.98876 0 27.98847 0.83536 25.93200 0.77398 4.87041 0.34885 4.51255 0.32322 55326.894140 0.000330 0.13366 0.01029 1.00000 0 28.01705 0.73679 25.95860 0.68266 3.74483 0.27101 3.46969 0.25109 55326.894730 0.000260 0.17306 0.01344 1.00000 0 27.51765 0.82668 25.49553 0.76593 4.76222 0.34110 4.41227 0.31604 55326.895245 0.000255 0.18519 0.01434 1.00000 0 26.69770 0.82154 24.73587 0.76117 4.94416 0.35144 4.58085 0.32561 55326.895781 0.000281 0.15149 0.01164 0.98969 0 29.47017 0.82149 27.30464 0.76112 4.46457 0.31978 4.13650 0.29628 55326.896333 0.000272 0.16509 0.01282 1.00000 0 27.63333 0.80943 25.60287 0.74995 4.56209 0.32803 4.22688 0.30393 55326.896857 0.000252 0.17160 0.01323 1.00000 0 28.83794 0.85709 26.71884 0.79411 4.94853 0.35217 4.58489 0.32629 55326.897491 0.000382 0.14373 0.01006 0.98485 0 27.83745 0.68255 25.79182 0.63240 4.00102 0.26243 3.70700 0.24315
