/* ** ** 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 58923.041609 0.000301 0.15929 0.01247 0.99038 0 26.20258 0.74924 23.98585 0.68586 4.17370 0.30428 3.82106 0.27857 58923.042185 0.000275 0.16787 0.01305 1.00000 0 27.35883 0.80764 24.89456 0.73485 4.59273 0.33042 4.18115 0.30081 58923.042737 0.000278 0.17114 0.01342 1.00000 0 26.78450 0.79411 24.35452 0.72201 4.58403 0.33279 4.16419 0.30237 58923.043264 0.000249 0.19393 0.01550 1.00000 0 26.11957 0.83787 23.58170 0.75642 5.06536 0.37083 4.57851 0.33511 58923.043782 0.000269 0.18196 0.01437 1.00000 0 25.39514 0.78790 23.24639 0.72123 4.62090 0.33554 4.22996 0.30714 58923.044326 0.000275 0.17950 0.01418 0.98947 0 26.15602 0.79883 23.31942 0.71220 4.69494 0.34219 4.18691 0.30524 58923.044899 0.000298 0.16588 0.01297 1.00000 0 25.85988 0.76220 23.14563 0.68213 4.28976 0.31061 3.83873 0.27801 58923.045477 0.000281 0.17724 0.01381 1.00000 0 26.09868 0.79389 23.22066 0.70634 4.62569 0.33193 4.11560 0.29533 58923.046047 0.000289 0.16786 0.01306 1.00000 0 26.56655 0.78819 23.67229 0.70230 4.45948 0.32084 3.97210 0.28577 58923.046597 0.000260 0.18570 0.01450 1.00000 0 26.29751 0.81628 23.74546 0.73708 4.88345 0.34993 4.41141 0.31609 58923.047147 0.000289 0.16738 0.01305 0.99000 0 26.67146 0.78398 23.96843 0.70454 4.46423 0.32247 4.01407 0.28994 58923.047737 0.000301 0.15726 0.01212 0.99038 0 27.09008 0.76702 24.49981 0.69362 4.26024 0.30532 3.85463 0.27620 58923.048310 0.000272 0.18143 0.01410 1.00000 0 26.05884 0.79711 23.39193 0.71550 4.72778 0.33784 4.24500 0.30339 58923.048883 0.000301 0.16923 0.01305 1.00000 0 25.06932 0.74337 22.64862 0.67157 4.24260 0.30205 3.83506 0.27298 58923.049473 0.000289 0.17190 0.01324 1.00000 0 26.20697 0.78067 23.31904 0.69464 4.50486 0.31985 4.00850 0.28460 58923.050139 0.000376 0.17529 0.01195 1.00000 0 25.27517 0.66666 22.69327 0.59856 4.43037 0.27845 3.98007 0.25014
