/* ** ** 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 59305.182447 0.000668 0.10586 0.00830 0.99567 0 17.30299 0.41293 15.82241 0.37756 1.83161 0.13672 1.67633 0.12511 59305.183749 0.000634 0.11574 0.00870 0.98630 0 17.40715 0.42207 15.95062 0.38675 2.01476 0.14332 1.84717 0.13139 59305.185033 0.000651 0.10818 0.00827 0.99111 0 17.78925 0.41981 16.34327 0.38569 1.92451 0.13984 1.76805 0.12847 59305.186376 0.000692 0.10694 0.00803 0.99582 0 17.20095 0.40278 15.68333 0.36722 1.83944 0.13130 1.67778 0.11975 59305.187675 0.000608 0.11497 0.00884 1.00000 0 17.69554 0.43450 16.24604 0.39890 2.03452 0.14822 1.86796 0.13609 59305.189070 0.000787 0.09282 0.00692 0.98162 0 17.63169 0.38219 16.13629 0.34974 1.63656 0.11681 1.49555 0.10675 59305.190392 0.000535 0.14030 0.01081 0.99459 0 16.69609 0.44895 15.33805 0.41243 2.34244 0.16920 2.15192 0.15543 59305.191992 0.001065 0.11203 0.00675 0.98370 0 16.98445 0.32256 15.55317 0.29537 1.90285 0.10882 1.74307 0.09965
