/* ** ** 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 56023.519689 0.000483 0.09022 0.01346 0.98802 0 7.57472 0.32365 6.68320 0.28553 0.68338 0.09765 0.60195 0.08601 56023.520633 0.000460 0.09237 0.01378 0.98113 0 7.83348 0.33683 6.89618 0.29651 0.72359 0.10340 0.63668 0.09097 56023.521637 0.000544 0.07994 0.01210 0.96809 0 7.64583 0.30759 6.71852 0.27029 0.61121 0.08917 0.53644 0.07825 56023.522716 0.000535 0.08632 0.01273 0.98919 0 7.15085 0.29775 6.34515 0.26419 0.61728 0.08730 0.54736 0.07741 56023.523798 0.000547 0.07604 0.01137 0.97884 0 7.92243 0.31152 6.99304 0.27497 0.60238 0.08694 0.53231 0.07684 56023.524834 0.000489 0.09015 0.01357 0.97633 0 7.45925 0.31813 6.62059 0.28234 0.67249 0.09707 0.59683 0.08616 56023.525714 0.000391 0.11090 0.01668 0.96296 0 7.83871 0.36878 6.87854 0.32359 0.86931 0.12421 0.76401 0.10916 56023.526538 0.000434 0.10696 0.01605 0.97333 0 7.33846 0.33748 6.44510 0.29639 0.78491 0.11210 0.68822 0.09833 56023.527398 0.000425 0.09949 0.01489 0.97959 0 7.83064 0.34919 6.93364 0.30918 0.77908 0.11131 0.68973 0.09855 56023.528188 0.000365 0.10504 0.01578 0.98413 0 8.69502 0.40330 7.59658 0.35233 0.91334 0.13051 0.80098 0.11444 56023.529096 0.000544 0.07687 0.01139 0.96809 0 8.05548 0.31481 7.09136 0.27712 0.61920 0.08847 0.54572 0.07797 56023.530439 0.000799 0.09116 0.01032 0.97464 0 7.94318 0.25871 6.99192 0.22772 0.72410 0.07854 0.63733 0.06914
