/* ** ** 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 59942.271430 0.000174 0.17037 0.01331 0.98333 0 42.63266 1.26146 39.36020 1.16463 7.26326 0.52537 6.70587 0.48506 59942.271783 0.000179 0.15715 0.01216 1.00000 0 44.17543 1.26671 40.78839 1.16959 6.94201 0.49898 6.40972 0.46072 59942.272154 0.000191 0.14937 0.01172 1.00000 0 43.09166 1.20938 39.77712 1.11636 6.43654 0.47151 5.94144 0.43524 59942.272527 0.000182 0.15223 0.01185 1.00000 0 45.01610 1.26974 41.03562 1.15744 6.85263 0.49699 6.24831 0.45315 59942.272912 0.000203 0.14077 0.01070 1.00000 0 44.98861 1.21219 40.92230 1.10266 6.33300 0.45001 5.75950 0.40930 59942.273303 0.000188 0.14503 0.01120 1.00000 0 47.06051 1.28994 42.37453 1.16145 6.82510 0.49291 6.15232 0.44433 59942.273673 0.000182 0.15447 0.01197 1.00000 0 45.29802 1.28739 40.63154 1.15476 6.99702 0.50424 6.27617 0.45229 59942.274029 0.000174 0.16245 0.01262 0.98333 0 46.25776 1.32956 41.48815 1.19247 7.51466 0.54214 6.73983 0.48624 59942.274402 0.000200 0.14550 0.01116 1.00000 0 44.09721 1.21369 39.55785 1.08876 6.41635 0.45947 5.75587 0.41217 59942.274790 0.000188 0.15040 0.01184 1.00000 0 44.05524 1.24431 39.89780 1.12687 6.62574 0.48676 6.00203 0.44086 59942.275146 0.000168 0.16850 0.01312 0.98276 0 45.21796 1.33551 41.15102 1.21523 7.61903 0.54898 6.93682 0.49990 59942.275487 0.000174 0.15906 0.01228 1.00000 0 46.07114 1.32631 41.68310 1.20000 7.32814 0.52476 6.61925 0.47400 59942.275855 0.000194 0.15529 0.01188 0.98507 0 43.09119 1.20851 38.93946 1.09204 6.69153 0.47620 6.04410 0.43009 59942.276231 0.000182 0.16180 0.01246 0.98413 0 44.61071 1.27692 40.01362 1.14534 7.21809 0.51616 6.47434 0.46298 59942.276752 0.000339 0.14164 0.00846 0.98875 0 45.09997 0.94447 40.45359 0.84716 6.38785 0.35724 5.72972 0.32043
