/* ** ** 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 58828.640604 0.000382 0.14477 0.01111 0.99242 0 22.54102 0.61877 20.92928 0.57453 3.26326 0.23393 3.03001 0.21721 58828.641397 0.000411 0.11731 0.00912 1.00000 0 25.34085 0.63124 23.37631 0.58227 2.97279 0.21900 2.74269 0.20210 58828.642161 0.000353 0.13877 0.01062 1.00000 0 25.84676 0.69262 23.44199 0.62812 3.58666 0.25715 3.25354 0.23323 58828.642873 0.000359 0.13799 0.01049 1.00000 0 25.10595 0.66951 23.30623 0.62152 3.46447 0.24666 3.21612 0.22897 58828.643616 0.000385 0.13742 0.01054 0.99248 0 23.59184 0.62631 21.88309 0.58095 3.24191 0.23339 3.00809 0.21656 58828.644319 0.000318 0.15831 0.01214 0.99091 0 25.48335 0.72715 23.12384 0.65980 4.03423 0.28724 3.65871 0.26048 58828.644999 0.000362 0.14703 0.01120 0.97600 0 24.39750 0.66170 22.22423 0.60273 3.58719 0.25539 3.26884 0.23273 58828.645957 0.000596 0.13696 0.00824 0.98589 0 25.13293 0.52356 22.99279 0.47889 3.44218 0.19432 3.14867 0.17772 58828.707947 0.000362 0.12972 0.00982 1.00000 0 26.50532 0.68324 24.57678 0.63353 3.43814 0.24465 3.19127 0.22709 58828.708613 0.000304 0.16550 0.01302 1.00000 0 24.39792 0.71793 22.56111 0.66385 4.03780 0.29473 3.73217 0.27241 58828.709249 0.000333 0.14330 0.01104 1.00000 0 25.95794 0.70765 24.01528 0.65470 3.71969 0.26817 3.43820 0.24778 58828.709923 0.000341 0.14601 0.01125 0.98305 0 25.56365 0.69685 23.38028 0.63728 3.73253 0.26897 3.40856 0.24564 58828.710609 0.000344 0.13246 0.01010 0.99160 0 27.50334 0.71811 25.40170 0.66317 3.64298 0.26087 3.36569 0.24102 58828.711237 0.000284 0.17383 0.01324 0.98980 0 26.19644 0.77083 24.25625 0.71372 4.55369 0.32004 4.21573 0.29626 58828.712007 0.000486 0.13681 0.00889 0.99405 0 26.95744 0.59994 24.64816 0.54854 3.68812 0.22517 3.37065 0.20574
