/* ** ** 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 56044.175579 0.000347 0.14213 0.03170 0.96667 0 9.64975 0.76401 2.79273 0.22111 1.37155 0.28600 0.39721 0.08282 56044.176276 0.000350 0.12818 0.02838 0.95868 0 10.63460 0.79093 3.10952 0.23122 1.36310 0.28427 0.39721 0.08282 56044.176936 0.000310 0.12459 0.03050 0.97196 0 10.27901 0.84988 3.01295 0.24912 1.28062 0.29510 0.37511 0.08644 56044.177561 0.000315 0.14793 0.03546 0.96330 0 8.81280 0.76057 2.58719 0.22326 1.30369 0.29152 0.38159 0.08533 56044.178212 0.000330 0.11085 0.02695 0.97368 0 10.72480 0.83014 3.16897 0.24527 1.18884 0.27399 0.35145 0.08099 56044.179239 0.000697 0.13500 0.02060 0.95436 0 10.98248 0.58228 3.19471 0.16937 1.48265 0.21219 0.43092 0.06168 56044.180515 0.000579 0.19143 0.02976 0.97000 0 9.10301 0.57016 2.67290 0.16741 1.74255 0.24796 0.51360 0.07307 56044.181536 0.000443 0.12046 0.02355 0.98693 0 10.95080 0.71084 3.26998 0.21226 1.31915 0.24325 0.39452 0.07275 56044.182306 0.000327 0.11982 0.02882 0.98230 0 10.13670 0.80877 2.97470 0.23733 1.21459 0.27564 0.35621 0.08085 56044.183006 0.000373 0.13858 0.02970 0.97674 0 9.78889 0.75457 2.86924 0.22116 1.35651 0.27132 0.39749 0.07950 56044.183996 0.000616 0.16218 0.02502 0.97183 0 9.99128 0.57529 2.95122 0.16991 1.62040 0.23194 0.47880 0.06853 56044.185197 0.000584 0.15834 0.02425 0.98515 0 10.96632 0.63631 3.20750 0.18610 1.73646 0.24607 0.50811 0.07199 56044.186076 0.000295 0.11533 0.02806 0.99020 0 11.43475 0.89464 3.35711 0.26266 1.31879 0.30387 0.38625 0.08901 56044.186933 0.000561 0.11910 0.02173 0.98454 0 10.33949 0.62839 3.03232 0.18426 1.23139 0.21180 0.36158 0.06217
