/* ** ** 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 55277.156637 0.000281 0.18124 0.01461 1.00000 0 25.12663 0.77322 22.20261 0.68312 4.55403 0.33923 4.02414 0.29957 55277.157172 0.000255 0.19950 0.01625 1.00000 0 25.73409 0.83995 22.01228 0.71835 5.13405 0.38308 4.38803 0.32719 55277.157679 0.000252 0.22416 0.01790 0.98851 0 23.66348 0.81143 20.51536 0.70339 5.30433 0.38263 4.59560 0.33146 55277.158188 0.000258 0.20308 0.01612 1.00000 0 25.52243 0.83068 21.87597 0.71201 5.18297 0.37533 4.44281 0.32172 55277.158709 0.000263 0.20613 0.01641 0.97802 0 25.02158 0.81234 21.57209 0.70032 5.15762 0.37497 4.44493 0.32315 55277.159250 0.000278 0.19031 0.01499 0.98958 0 25.21139 0.79642 21.84437 0.68993 4.79798 0.34615 4.16023 0.30006 55277.159777 0.000249 0.21007 0.01670 1.00000 0 25.65621 0.85350 22.00586 0.73206 5.38966 0.38925 4.62109 0.33376 55277.160251 0.000226 0.23302 0.01835 1.00000 0 25.63127 0.88836 22.05870 0.76448 5.97262 0.42235 5.13676 0.36322 55277.160786 0.000310 0.17169 0.01324 0.99065 0 25.45896 0.75432 21.88614 0.64840 4.37109 0.31115 3.76275 0.26783 55277.161339 0.000243 0.20319 0.01634 1.00000 0 26.23364 0.86205 22.96377 0.75456 5.33046 0.39117 4.66405 0.34224 55277.161834 0.000252 0.21602 0.01713 0.98851 0 24.63977 0.82162 21.38523 0.71307 5.32261 0.38286 4.61890 0.33227 55277.162375 0.000289 0.17758 0.01411 1.00000 0 25.34390 0.77187 22.09238 0.67284 4.50052 0.33025 3.91780 0.28748 55277.162945 0.000281 0.19738 0.01579 0.97938 0 23.80512 0.75771 20.88377 0.66470 4.69873 0.34480 4.12400 0.30261 55277.163495 0.000269 0.19747 0.01552 0.96774 0 25.91963 0.81669 22.48112 0.70839 5.11828 0.36865 4.43797 0.31970 55277.164027 0.000263 0.20315 0.01626 0.98901 0 24.89575 0.81120 21.41628 0.69784 5.05760 0.36967 4.35102 0.31801 55277.164560 0.000269 0.20613 0.01609 1.00000 0 24.35746 0.79790 20.98681 0.68743 5.02091 0.35562 4.33181 0.30678 55277.165104 0.000275 0.19140 0.01497 1.00000 0 25.48492 0.80084 21.83759 0.68622 4.87786 0.34948 4.17934 0.29945 55277.165653 0.000275 0.19154 0.01532 1.00000 0 24.82990 0.78928 21.52793 0.68426 4.75597 0.34909 4.12400 0.30261 55277.166220 0.000292 0.18405 0.01450 0.97030 0 25.02755 0.76622 21.77882 0.66680 4.60638 0.33450 4.01436 0.29146 55277.166756 0.000243 0.21687 0.01746 0.98810 0 24.94346 0.84314 21.73281 0.73461 5.40938 0.39537 4.71797 0.34483 55277.167517 0.000518 0.17580 0.01065 0.99441 0 25.17615 0.57673 21.90451 0.50178 4.42602 0.24821 3.85372 0.21599
