/* ** ** 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 59589.175710 0.000680 0.11427 0.00876 0.97447 0 16.96725 0.41352 15.02745 0.36624 1.93881 0.14090 1.71746 0.12476 59589.177076 0.000686 0.11077 0.00864 0.97890 0 17.06002 0.41424 15.10096 0.36663 1.88978 0.14011 1.67144 0.12391 59589.178441 0.000680 0.11157 0.00859 0.97021 0 17.33090 0.41751 15.38924 0.37073 1.93353 0.14141 1.71692 0.12557 59589.179862 0.000741 0.10148 0.00776 0.97656 0 17.48314 0.40045 15.50991 0.35526 1.77422 0.12941 1.57384 0.11480 59589.181271 0.000668 0.12256 0.00940 0.98701 0 16.09297 0.40628 14.15973 0.35742 1.97243 0.14290 1.73378 0.12561 59589.182620 0.000680 0.11274 0.00872 0.98298 0 16.95268 0.41056 15.03714 0.36417 1.91127 0.14035 1.69532 0.12449 59589.184341 0.001042 0.10876 0.00685 0.98333 0 17.14384 0.33311 15.17458 0.29484 1.86465 0.11179 1.65046 0.09896
