/* ** ** 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 59362.152236 0.000362 0.11403 0.01753 1.00000 0 7.67619 0.37149 6.94960 0.33633 0.87534 0.12773 0.79108 0.11545 59362.153018 0.000420 0.10351 0.01579 0.96552 0 7.55796 0.34707 6.75998 0.31042 0.78235 0.11381 0.69984 0.10179 59362.153787 0.000350 0.11866 0.01796 0.95041 0 8.02875 0.38904 7.26188 0.35189 0.95273 0.13663 0.86149 0.12355 59362.154580 0.000443 0.09022 0.01332 0.97386 0 8.35011 0.35439 7.45839 0.31656 0.75332 0.10654 0.67226 0.09507 59362.155434 0.000411 0.10517 0.01570 0.97183 0 7.86272 0.36343 6.97011 0.32217 0.82689 0.11738 0.73243 0.10397 59362.156753 0.000909 0.14667 0.01279 0.98777 0 7.77000 0.24106 6.88216 0.21349 1.13964 0.09287 1.00873 0.08223 59362.223374 0.000894 0.08318 0.00882 0.98918 0 8.55696 0.25169 7.72609 0.22725 0.71181 0.07247 0.64220 0.06538
