/* ** ** 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 59365.197802 0.000350 0.08645 0.01305 0.96694 0 10.88322 0.45545 9.71959 0.40671 0.94085 0.13642 0.83909 0.12167 59365.199170 0.001019 0.11798 0.00906 0.98295 0 10.65053 0.26239 9.59499 0.23639 1.25659 0.09139 1.13208 0.08234 59365.200524 0.000336 0.09282 0.01406 0.98276 0 10.32943 0.45394 9.25974 0.40694 0.95879 0.13904 0.86117 0.12487 59365.201167 0.000307 0.10225 0.01491 0.99057 0 10.73446 0.48396 9.70298 0.43745 1.09760 0.15221 0.99213 0.13758 59365.202518 0.001045 0.11457 0.00879 0.98338 0 10.76070 0.26124 9.64175 0.23406 1.23290 0.08967 1.10337 0.08025 59365.203866 0.000304 0.10033 0.01544 0.97143 0 10.58576 0.48125 9.50685 0.43211 1.06204 0.15610 0.95272 0.13991 59365.204509 0.000339 0.09722 0.01379 0.98291 0 11.16264 0.47054 10.03489 0.42294 1.08518 0.14692 0.97563 0.13209 59365.205160 0.000312 0.09607 0.01444 1.00000 0 10.75319 0.47954 9.66180 0.43081 1.03310 0.14823 0.92756 0.13311 59365.206552 0.001079 0.11318 0.00878 0.97051 0 10.28217 0.25153 9.25825 0.22646 1.16372 0.08563 1.04602 0.07698
