/* ** ** 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 55348.953636 0.000367 0.13067 0.02015 0.99213 0 6.59677 0.34140 5.95292 0.30805 0.86202 0.12523 0.77832 0.11304 55348.954331 0.000327 0.14297 0.02194 0.99115 0 6.82674 0.37390 6.18532 0.33875 0.97599 0.13988 0.88498 0.12683 55348.955074 0.000417 0.11173 0.01733 0.99306 0 6.64445 0.32467 6.07201 0.29670 0.74238 0.10928 0.67845 0.09987 55348.955951 0.000460 0.10002 0.01503 0.98113 0 6.98755 0.31637 6.36652 0.28823 0.69890 0.10015 0.63537 0.09105 55348.956842 0.000431 0.11321 0.01713 0.98658 0 6.55350 0.31731 5.96359 0.28871 0.74194 0.10634 0.67427 0.09663 55348.957687 0.000414 0.11084 0.01673 0.97902 0 6.98961 0.33078 6.38823 0.30232 0.77470 0.11102 0.70798 0.10146 55348.958529 0.000428 0.11894 0.01761 0.96622 0 6.59268 0.31697 6.01325 0.28910 0.78414 0.10981 0.71448 0.10005 55348.959377 0.000420 0.10659 0.01649 0.99310 0 6.92088 0.32827 6.31554 0.29955 0.73771 0.10859 0.67374 0.09918 55348.960207 0.000411 0.12552 0.01886 0.98592 0 6.23652 0.31599 5.69945 0.28878 0.78282 0.11071 0.71548 0.10118 55348.961047 0.000428 0.11201 0.01692 0.97973 0 6.69415 0.31952 6.08853 0.29062 0.74980 0.10746 0.68357 0.09796 55348.961831 0.000356 0.12891 0.01962 0.97561 0 7.01162 0.35891 6.40801 0.32801 0.90384 0.12953 0.82598 0.11837 55348.962548 0.000362 0.14127 0.02133 0.96000 0 6.46596 0.34252 5.90845 0.31298 0.91344 0.12918 0.83472 0.11805 55348.963292 0.000382 0.12292 0.01841 0.96970 0 6.97202 0.34331 6.36756 0.31354 0.85700 0.12120 0.78255 0.11067 55348.964455 0.000781 0.10302 0.01156 0.98889 0 7.06824 0.24262 6.44427 0.22120 0.72819 0.07776 0.66385 0.07089
