/* ** ** 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 57473.988707 0.000312 0.08490 0.01279 0.98148 0 12.00453 0.49811 10.94333 0.45408 1.01913 0.14763 0.92908 0.13458 57473.990087 0.001068 0.10304 0.00772 0.97832 0 11.87225 0.27105 10.74259 0.24524 1.22335 0.08733 1.10610 0.07895 57473.991473 0.000318 0.08798 0.01299 1.00000 0 11.50638 0.48855 10.36508 0.44004 1.01229 0.14317 0.91061 0.12878 57473.992095 0.000304 0.08662 0.01306 0.99048 0 12.15752 0.51158 10.96977 0.46155 1.05307 0.15249 0.94695 0.13717 57473.993435 0.001036 0.10500 0.00781 0.99721 0 11.78859 0.27227 10.69112 0.24692 1.23782 0.08753 1.12232 0.07936 57473.994870 0.000399 0.09432 0.01219 0.99275 0 11.51827 0.43885 10.40258 0.39633 1.08636 0.13414 0.98206 0.12121 57473.995587 0.000318 0.07692 0.01156 1.00000 0 12.95291 0.51781 11.67000 0.46650 0.99640 0.14428 0.89530 0.12969 57473.996976 0.001071 0.10121 0.00759 0.98919 0 11.92140 0.27221 10.77139 0.24594 1.20652 0.08614 1.09099 0.07787 57473.999002 0.000955 0.09305 0.00757 0.98485 0 12.27586 0.29034 11.15305 0.26377 1.14232 0.08886 1.03754 0.08070
