/* ** ** 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 59676.028810 0.000391 0.14567 0.01115 1.00000 0 23.45483 0.64259 20.32393 0.55683 3.41660 0.24421 2.95573 0.21125 59676.029594 0.000394 0.14719 0.01153 1.00000 0 22.44317 0.63186 19.57412 0.55090 3.30340 0.24141 2.87904 0.21047 59676.030364 0.000376 0.15270 0.01193 0.98462 0 22.95860 0.64406 20.13191 0.56474 3.50584 0.25559 3.07463 0.22417 59676.031108 0.000367 0.16261 0.01276 0.98425 0 21.98790 0.63902 19.36232 0.56271 3.57544 0.26068 3.14843 0.22955 59676.031845 0.000370 0.15388 0.01207 1.00000 0 22.94464 0.65367 20.20062 0.57550 3.53069 0.25808 3.10875 0.22724 59676.032644 0.000428 0.14444 0.01128 0.97973 0 21.41420 0.58817 18.70480 0.51376 3.09304 0.22619 2.70034 0.19740 59676.033454 0.000382 0.14895 0.01182 1.00000 0 22.60377 0.64202 19.72282 0.56019 3.36688 0.24939 2.93866 0.21772 59676.034189 0.000353 0.17380 0.01360 1.00000 0 21.25253 0.64516 18.62862 0.56556 3.69372 0.26642 3.23932 0.23366 59676.034959 0.000417 0.14780 0.01143 0.99306 0 21.32358 0.59503 18.69818 0.52171 3.15168 0.22733 2.76361 0.19935 59676.035749 0.000373 0.16964 0.01330 0.95349 0 21.81849 0.64033 18.94864 0.55619 3.70123 0.26904 3.21591 0.23385 59676.036819 0.000697 0.14517 0.00858 0.99307 0 22.12597 0.46823 19.39046 0.41037 3.21194 0.17737 2.81629 0.15551 59676.964471 0.000573 0.12758 0.01003 0.98485 0 19.39159 0.50468 15.64331 0.40686 2.47389 0.18345 1.98938 0.14737 59676.965551 0.000506 0.13688 0.01066 0.98857 0 20.16536 0.54294 16.53462 0.44518 2.76023 0.20177 2.26340 0.16545 59676.966587 0.000530 0.13154 0.01031 0.98907 0 19.92648 0.52286 16.37809 0.42975 2.62107 0.19363 2.15432 0.15916 59676.967596 0.000480 0.15441 0.01208 0.99398 0 19.09206 0.54244 15.49266 0.44014 2.94805 0.21484 2.38528 0.17389 59676.968760 0.000683 0.14307 0.00943 0.99153 0 19.96415 0.46488 16.24236 0.37815 2.85621 0.17612 2.32403 0.14329
