/* ** ** 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 59334.054574 0.000512 0.13460 0.01026 0.99435 0 19.24689 0.50539 16.72676 0.43916 2.59072 0.18545 2.25561 0.16143 59334.055590 0.000503 0.14161 0.01075 0.99425 0 18.41088 0.49599 16.30480 0.43922 2.60711 0.18511 2.30890 0.16392 59334.056655 0.000561 0.12917 0.00997 0.98969 0 17.77040 0.45990 15.80888 0.40914 2.29545 0.16695 2.04208 0.14852 59334.057676 0.000460 0.14385 0.01105 0.98742 0 19.69859 0.53382 17.52462 0.47490 2.83356 0.20361 2.52076 0.18113 59334.058628 0.000492 0.13851 0.01061 0.98235 0 19.23629 0.50961 17.10973 0.45327 2.66435 0.19145 2.36982 0.17028 59334.059658 0.000538 0.12974 0.00997 0.97312 0 18.82195 0.48163 16.74954 0.42859 2.44189 0.17689 2.17296 0.15741 59334.060651 0.000454 0.14914 0.01144 0.99363 0 19.17708 0.52999 17.06370 0.47158 2.86004 0.20468 2.54479 0.18212 59334.061666 0.000561 0.13027 0.01011 0.98454 0 17.69362 0.45908 15.74024 0.40840 2.30495 0.16856 2.05042 0.14995 59334.062746 0.000518 0.13613 0.01036 1.00000 0 18.40133 0.48618 16.37463 0.43263 2.50490 0.17881 2.22900 0.15911 59334.063923 0.000660 0.13924 0.00934 0.97807 0 18.67716 0.44226 16.61706 0.39348 2.60062 0.16329 2.31372 0.14527
