/* ** ** 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 59262.163942 0.000773 0.12786 0.00984 0.98502 0 13.20253 0.33741 11.71754 0.29945 1.68803 0.12257 1.49584 0.10861 59262.165600 0.000885 0.11874 0.00931 0.98693 0 12.31511 0.30755 10.84181 0.27074 1.46227 0.10872 1.28525 0.09557 59262.167206 0.000715 0.14250 0.01085 0.98785 0 12.97705 0.35008 11.46163 0.30915 1.84924 0.13165 1.63464 0.11635 59262.168632 0.000712 0.14212 0.01101 0.98374 0 13.03047 0.35343 11.45323 0.31061 1.85192 0.13444 1.62564 0.11803 59262.170085 0.000741 0.14298 0.01092 0.98047 0 12.67428 0.34080 11.13127 0.29930 1.81218 0.12953 1.58980 0.11362 59262.172203 0.001377 0.11947 0.00735 0.98109 0 12.62155 0.25140 10.97655 0.21863 1.50788 0.08772 1.31080 0.07625
