/* ** ** 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 59306.125950 0.000460 0.13757 0.01061 0.98742 0 20.50748 0.54652 18.30489 0.48776 2.82128 0.20428 2.51906 0.18234 59306.126897 0.000486 0.12285 0.00954 0.98810 0 21.76846 0.55306 19.19643 0.48770 2.67425 0.19616 2.36087 0.17313 59306.127843 0.000460 0.13300 0.01037 0.98742 0 21.06228 0.55606 18.73640 0.49463 2.80123 0.20545 2.49620 0.18306 59306.128798 0.000495 0.12527 0.00956 0.98246 0 21.49420 0.54821 18.86750 0.48118 2.69255 0.19361 2.36480 0.17007 59306.129779 0.000486 0.12902 0.00982 0.98810 0 21.17981 0.54341 18.54187 0.47575 2.73270 0.19572 2.39204 0.17135 59306.130771 0.000506 0.12088 0.00917 1.00000 0 21.45433 0.53518 18.77217 0.46828 2.59350 0.18580 2.26902 0.16254 59306.131746 0.000469 0.13965 0.01059 0.99383 0 20.19011 0.53953 17.81825 0.47614 2.81953 0.20017 2.48991 0.17676 59306.132643 0.000428 0.14395 0.01124 0.98649 0 21.40990 0.58513 18.74269 0.51222 3.08192 0.22540 2.69800 0.19733 59306.133505 0.000434 0.14514 0.01130 0.99333 0 20.69939 0.56930 18.20456 0.50060 3.00430 0.21892 2.64227 0.19251 59306.135004 0.001065 0.11561 0.00638 0.99185 0 20.58247 0.35973 18.16287 0.31743 2.37960 0.12464 2.09745 0.10988
