/* ** ** 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 59232.088537 0.000301 0.14572 0.02261 0.98077 0 7.62730 0.41787 6.62188 0.36281 1.11142 0.16136 0.96173 0.13962 59232.089145 0.000307 0.15432 0.02413 0.99057 0 7.12670 0.40080 6.17851 0.34747 1.09983 0.16046 0.95269 0.13899 59232.089877 0.000425 0.11905 0.01786 0.97279 0 6.91865 0.33752 5.94481 0.28996 0.82367 0.11683 0.70724 0.10031 59232.090641 0.000339 0.11516 0.01745 1.00000 0 8.65204 0.42640 7.36854 0.36322 0.99634 0.14277 0.84728 0.12140 59232.091347 0.000367 0.11997 0.01863 0.96063 0 7.82311 0.38902 6.64572 0.33047 0.93850 0.13806 0.79558 0.11704 59232.092368 0.000654 0.14308 0.01469 0.97788 0 8.16246 0.29824 6.91280 0.25256 1.16791 0.11203 0.99245 0.09519 59232.093427 0.000405 0.10270 0.01585 1.00000 0 7.86343 0.36760 6.72772 0.31451 0.80754 0.11876 0.69329 0.10199 59232.094217 0.000385 0.11902 0.01781 0.97744 0 7.62412 0.37325 6.48476 0.31743 0.90740 0.12834 0.77051 0.10897 59232.094999 0.000396 0.10218 0.01557 0.97080 0 8.50684 0.39324 7.21147 0.33334 0.86922 0.12618 0.73756 0.10708 59232.095754 0.000359 0.12319 0.01829 0.98387 0 8.01989 0.39606 6.80534 0.33604 0.98794 0.13835 0.83746 0.11727 59232.096442 0.000330 0.13594 0.02102 0.98246 0 7.54678 0.40169 6.44905 0.34319 1.02592 0.14896 0.87586 0.12715 59232.097334 0.000561 0.11814 0.01469 0.98454 0 7.70496 0.31269 6.56529 0.26640 0.91028 0.10700 0.77581 0.09116
