/* ** ** 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 58123.911011 0.000414 0.28152 0.01019 1.00000 0 53.01765 0.90069 49.42783 0.83971 14.92550 0.47679 13.91630 0.44455 58123.911853 0.000428 0.27605 0.00999 0.98034 0 53.49913 0.90545 49.78661 0.84257 14.76869 0.47222 13.73770 0.43923 58123.912684 0.000402 0.28562 0.01036 0.99281 0 54.57372 0.93360 50.90980 0.87085 15.58756 0.49844 14.53332 0.46475 58123.913497 0.000411 0.28490 0.01044 1.00000 0 52.82194 0.91001 48.86699 0.84185 15.04871 0.48650 13.91485 0.44988 58123.914287 0.000379 0.30001 0.01110 1.00000 0 53.81408 0.95618 50.28539 0.89348 16.14478 0.52367 15.08603 0.48933 58123.915059 0.000394 0.30006 0.01110 1.00000 0 52.23949 0.92356 48.37115 0.85514 15.67473 0.50952 14.51063 0.47180 58123.915832 0.000379 0.30698 0.01125 1.00000 0 53.35737 0.95164 49.62983 0.88508 16.37986 0.52416 15.23971 0.48767 58123.916605 0.000394 0.29266 0.01073 1.00000 0 53.84032 0.93868 49.86654 0.86931 15.75665 0.50843 14.58766 0.47066 58123.917389 0.000391 0.29256 0.01069 1.00000 0 55.26758 0.95942 50.36513 0.87428 16.16898 0.51989 14.74632 0.47414 58123.918170 0.000391 0.30273 0.01110 1.00000 0 52.31017 0.92835 48.61179 0.86268 15.83597 0.50811 14.71397 0.47206 58123.918943 0.000382 0.30619 0.01135 1.00000 0 52.85524 0.94204 48.86389 0.87085 16.18373 0.52589 14.96553 0.48633 58123.919718 0.000394 0.28674 0.01046 1.00000 0 55.46528 0.95835 50.94033 0.88013 15.90418 0.51121 14.59974 0.46928 58123.920818 0.000706 0.28813 0.00783 1.00000 0 55.46608 0.71108 51.17841 0.65610 15.98163 0.38316 14.74610 0.35350
