/* ** ** 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 56724.386444 0.000231 0.17380 0.01360 1.00000 0 31.35472 0.93486 28.31218 0.84414 5.44943 0.39431 4.92324 0.35618 56724.386948 0.000272 0.16119 0.01256 1.00000 0 29.26297 0.84660 25.98311 0.75167 4.71698 0.34117 4.18999 0.30313 56724.387463 0.000243 0.17408 0.01368 1.00000 0 30.15759 0.90621 26.98186 0.81070 5.24976 0.38123 4.70408 0.34166 56724.387978 0.000272 0.15876 0.01220 0.98936 0 29.82289 0.84927 26.95079 0.76748 4.73476 0.33786 4.27897 0.30534 56724.388531 0.000281 0.15344 0.01196 0.98969 0 29.41868 0.82770 26.64528 0.74967 4.51398 0.32808 4.08851 0.29716 56724.389043 0.000231 0.18318 0.01426 1.00000 0 30.23176 0.92935 27.18054 0.83551 5.53791 0.39600 4.98232 0.35625 56724.389514 0.000240 0.18919 0.01459 1.00000 0 28.54190 0.88212 25.85288 0.79901 5.39978 0.38146 4.89105 0.34552 56724.390004 0.000249 0.17040 0.01334 0.97674 0 30.68194 0.89911 27.79131 0.81440 5.22810 0.37945 4.73556 0.34371 56724.390495 0.000243 0.17290 0.01332 1.00000 0 30.34598 0.90630 27.49458 0.82114 5.24680 0.37270 4.75364 0.33767 56724.391002 0.000263 0.16007 0.01227 0.98901 0 30.64966 0.87184 27.76185 0.78969 4.90610 0.34921 4.44386 0.31630 56724.391549 0.000284 0.15315 0.01179 0.98980 0 29.49422 0.82545 26.69361 0.74707 4.51701 0.32380 4.08848 0.29309 56724.392075 0.000243 0.17135 0.01314 1.00000 0 31.16876 0.91816 28.03614 0.82584 5.34082 0.37827 4.80897 0.34057 56724.392550 0.000231 0.18064 0.01403 1.00000 0 30.65336 0.93073 27.76478 0.84302 5.53716 0.39570 5.01538 0.35841 56724.393059 0.000278 0.15227 0.01184 1.00000 0 29.79458 0.83952 26.98737 0.76042 4.53686 0.32888 4.10938 0.29789 56724.393603 0.000266 0.15230 0.01175 1.00000 0 31.38716 0.88224 28.33478 0.79643 4.78024 0.34343 4.31765 0.31014 56724.394121 0.000252 0.16234 0.01266 1.00000 0 30.89882 0.89662 27.90420 0.80969 5.01614 0.36299 4.52711 0.32752 56724.394596 0.000223 0.19660 0.01529 0.98701 0 29.50478 0.93287 26.72460 0.84497 5.80061 0.41204 5.25402 0.37321 56724.395096 0.000278 0.15386 0.01185 0.98958 0 30.08523 0.84424 27.13581 0.76148 4.62890 0.33187 4.17455 0.29926 56724.395614 0.000240 0.17673 0.01368 1.00000 0 30.22859 0.90794 27.30308 0.82006 5.34228 0.38101 4.82637 0.34422 56724.396112 0.000258 0.16201 0.01244 1.00000 0 30.62410 0.88428 27.73812 0.80095 4.96134 0.35314 4.49379 0.31986 56724.396783 0.000414 0.17181 0.01025 1.00000 0 30.11679 0.68936 27.15062 0.62147 5.17441 0.28502 4.66456 0.25694
