/* ** ** 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 59932.269715 0.000541 0.10479 0.00792 0.99465 0 22.03530 0.51243 20.30666 0.47218 2.30909 0.16599 2.12895 0.15301 59932.270855 0.000599 0.09119 0.00695 0.99034 0 22.64691 0.49143 21.06273 0.45705 2.06510 0.15089 1.92072 0.14034 59932.272120 0.000666 0.08209 0.00617 0.99565 0 22.55585 0.46614 20.98060 0.43359 1.85170 0.13381 1.72238 0.12447 59932.273329 0.000544 0.09961 0.00758 0.99468 0 22.75967 0.51807 21.09830 0.48025 2.26720 0.16472 2.10087 0.15265 59932.274515 0.000642 0.09066 0.00668 0.98198 0 21.91249 0.46715 20.37539 0.43438 1.98655 0.14012 1.84711 0.13029 59932.275835 0.000677 0.08319 0.00620 0.97436 0 22.62624 0.46201 20.99693 0.42873 1.88230 0.13493 1.74556 0.12513 59932.277154 0.000642 0.08898 0.00662 0.97748 0 22.24785 0.46988 20.69172 0.43702 1.97972 0.14115 1.84124 0.13128 59932.278390 0.000593 0.09511 0.00719 0.99024 0 21.96379 0.48747 20.42788 0.45338 2.08907 0.15097 1.94298 0.14041 59932.279524 0.000541 0.10230 0.00780 0.98930 0 22.31918 0.51440 20.75811 0.47842 2.28328 0.16590 2.12359 0.15430 59932.280661 0.000596 0.09070 0.00689 0.98544 0 22.96821 0.49621 21.36206 0.46151 2.08313 0.15179 1.93747 0.14117 59932.281859 0.000602 0.09388 0.00702 0.99038 0 22.25425 0.48829 20.57487 0.45144 2.08926 0.14934 1.92983 0.13795 59932.283063 0.000602 0.09593 0.00716 0.99038 0 21.73925 0.47860 20.21915 0.44514 2.08538 0.14869 1.93956 0.13829 59932.284270 0.000605 0.08877 0.00672 0.98086 0 23.21163 0.49404 21.58905 0.45951 2.06045 0.14971 1.91641 0.13925 59932.285493 0.000619 0.09357 0.00682 0.99065 0 22.73684 0.48666 21.01522 0.44979 2.12744 0.14833 1.96971 0.13733
