/* ** ** 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 57792.210507 0.000593 0.15869 0.01231 0.98537 0 13.81020 0.39486 12.33060 0.35256 2.19157 0.15809 1.95630 0.14113 57792.211601 0.000501 0.17484 0.01392 1.00000 0 14.49152 0.44019 12.88324 0.39133 2.53370 0.18651 2.25247 0.16581 57792.212738 0.000637 0.14209 0.01107 0.97273 0 14.52104 0.39159 12.87648 0.34724 2.06333 0.15085 1.82948 0.13377 57792.214026 0.000651 0.14078 0.01095 0.98222 0 14.20793 0.38358 12.64706 0.34144 2.00018 0.14586 1.78060 0.12985 57792.215264 0.000587 0.15051 0.01168 0.97044 0 14.99355 0.41631 13.33308 0.37020 2.25668 0.16347 2.00682 0.14537 57792.216474 0.000622 0.14096 0.01085 0.98140 0 14.97088 0.40254 13.28462 0.35718 2.11030 0.15226 1.87285 0.13511 57792.217750 0.000654 0.13380 0.01015 0.98673 0 15.02484 0.39361 13.36650 0.35017 2.01028 0.14310 1.78850 0.12731 57792.218997 0.000593 0.14694 0.01164 0.99024 0 14.61698 0.40778 13.00175 0.36272 2.14785 0.15918 1.91057 0.14159 57792.220556 0.000966 0.16178 0.00971 0.97904 0 14.34350 0.31495 12.75585 0.28009 2.32047 0.12968 2.06372 0.11533
