/* ** ** 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 58627.918069 0.000214 0.23694 0.01879 0.98649 0 26.92011 0.92830 23.12928 0.79758 6.37844 0.45545 5.48024 0.39132 58627.918537 0.000255 0.19280 0.01513 1.00000 0 27.22794 0.85957 23.39376 0.73853 5.24945 0.37720 4.51023 0.32408 58627.919026 0.000234 0.23714 0.01889 1.00000 0 24.06823 0.84488 20.67899 0.72591 5.70747 0.40811 4.90376 0.35064 58627.919510 0.000249 0.21740 0.01721 1.00000 0 24.88603 0.83323 21.38163 0.71590 5.41013 0.38818 4.64829 0.33352 58627.919981 0.000223 0.23046 0.01838 1.00000 0 26.03227 0.89987 22.36646 0.77316 5.99937 0.43108 5.15455 0.37038 58627.920424 0.000220 0.22893 0.01819 1.00000 0 26.76166 0.93212 22.99314 0.80086 6.12666 0.43747 5.26391 0.37587 58627.920904 0.000260 0.20578 0.01612 0.98889 0 25.36965 0.82097 21.79715 0.70536 5.22064 0.37235 4.48548 0.31991 58627.921414 0.000249 0.21184 0.01666 1.00000 0 25.50445 0.84577 21.91297 0.72667 5.40276 0.38534 4.64195 0.33107 58627.921903 0.000240 0.23312 0.01847 0.96386 0 24.78921 0.84654 21.29845 0.72733 5.77882 0.41321 4.96506 0.35502 58627.922360 0.000217 0.24260 0.01956 1.00000 0 25.18711 0.89841 21.64032 0.77190 6.11035 0.44185 5.24991 0.37963 58627.922823 0.000246 0.22833 0.01804 1.00000 0 24.11150 0.82576 20.71617 0.70948 5.50538 0.39211 4.73013 0.33690 58627.923326 0.000258 0.21047 0.01645 0.98876 0 25.10555 0.82066 21.57024 0.70510 5.28399 0.37502 4.53991 0.32221 58627.923850 0.000266 0.18917 0.01496 1.00000 0 26.25474 0.82418 22.55760 0.70812 4.96667 0.36050 4.26727 0.30973 58627.924565 0.000448 0.22266 0.01274 0.99442 0 25.78663 0.63195 22.15541 0.54296 5.74152 0.29682 4.93302 0.25502 58627.968083 0.000263 0.20479 0.01649 0.98901 0 22.55755 0.73447 21.17693 0.68952 4.61965 0.34010 4.33691 0.31929 58627.968590 0.000243 0.22892 0.01801 1.00000 0 22.33155 0.76953 20.96477 0.72243 5.11204 0.36159 4.79916 0.33946 58627.969110 0.000278 0.18205 0.01425 1.00000 0 24.16597 0.74050 22.68691 0.69517 4.39943 0.31700 4.13016 0.29760 58627.969620 0.000231 0.22363 0.01751 0.98750 0 24.30626 0.81518 22.81861 0.76529 5.43558 0.38447 5.10290 0.36094 58627.970337 0.000486 0.21363 0.01237 1.00000 0 22.18148 0.53593 20.82388 0.50313 4.73869 0.24934 4.44866 0.23408
