/* ** ** 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 56765.658816 0.000527 0.17164 0.01321 0.99451 0 14.01225 0.41626 12.90614 0.38341 2.40502 0.17073 2.21478 0.15723 56765.660009 0.000666 0.13244 0.01041 0.97826 0 14.30219 0.37611 13.01527 0.34222 1.89424 0.14026 1.72492 0.12767 56765.661296 0.000622 0.14776 0.01135 0.99535 0 13.65090 0.37783 12.54603 0.34724 2.01707 0.14449 1.85551 0.13292 56765.662497 0.000579 0.15658 0.01214 0.97000 0 14.23219 0.40429 12.99992 0.36929 2.22848 0.16072 2.03755 0.14691 56765.663654 0.000579 0.14839 0.01168 0.99500 0 14.32454 0.40188 13.20397 0.37044 2.12566 0.15630 1.95930 0.14407 56765.664812 0.000579 0.16097 0.01240 0.99000 0 13.72819 0.39382 12.53220 0.35953 2.20985 0.15792 2.01556 0.14402 56765.666062 0.000671 0.13150 0.01002 0.99138 0 14.36824 0.37307 13.13860 0.34113 1.88946 0.13534 1.72643 0.12367 56765.667390 0.000657 0.13730 0.01065 0.98238 0 13.99010 0.37194 12.86478 0.34200 1.92088 0.13997 1.76546 0.12863 56765.668657 0.000611 0.14186 0.01095 0.98578 0 14.54030 0.39024 13.40368 0.35974 2.06265 0.14931 1.90141 0.13763 56765.670046 0.000778 0.14247 0.00979 0.98885 0 14.29974 0.34464 13.11950 0.31618 2.03732 0.13104 1.87091 0.12032
