/* ** ** 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 57753.164818 0.000266 0.19451 0.01553 1.00000 0 24.40778 0.78107 21.86954 0.69968 4.74762 0.34728 4.25521 0.31117 57753.165324 0.000240 0.23869 0.01936 0.98795 0 23.09468 0.81910 20.09013 0.71247 5.51248 0.40217 4.79857 0.34997 57753.165813 0.000249 0.21067 0.01660 1.00000 0 24.61221 0.81722 22.02075 0.73118 5.18502 0.37062 4.63948 0.33164 57753.166285 0.000223 0.21413 0.01681 1.00000 0 27.07438 0.90500 24.31216 0.81266 5.79753 0.41166 5.20562 0.36963 57753.166721 0.000214 0.23872 0.01935 1.00000 0 24.78025 0.87730 22.27439 0.78859 5.91548 0.43143 5.31734 0.38781 57753.167155 0.000220 0.24015 0.01913 1.00000 0 24.36808 0.85636 21.86074 0.76824 5.85189 0.41830 5.24993 0.37527 57753.167633 0.000258 0.20089 0.01600 1.00000 0 24.53190 0.80058 21.99853 0.71790 4.92811 0.35796 4.41929 0.32100 57753.168105 0.000214 0.23382 0.01884 1.00000 0 25.42409 0.89775 22.84597 0.80672 5.94458 0.43065 5.34216 0.38701 57753.168547 0.000229 0.22667 0.01805 0.98734 0 25.03593 0.85251 22.46249 0.76488 5.67493 0.40837 5.09176 0.36641 57753.168999 0.000223 0.24014 0.01909 1.00000 0 24.17190 0.85078 21.68727 0.76332 5.80455 0.41386 5.20777 0.37131 57753.169462 0.000240 0.21074 0.01689 1.00000 0 25.07681 0.83424 22.49665 0.74840 5.28471 0.38543 4.74076 0.34576 57753.169910 0.000208 0.24447 0.01969 1.00000 0 25.03810 0.89546 22.45038 0.80291 6.12107 0.44163 5.48825 0.39597 57753.170335 0.000217 0.23380 0.01881 1.00000 0 25.13265 0.88003 22.54638 0.78947 5.87593 0.42568 5.27094 0.38185 57753.170781 0.000229 0.24158 0.01907 1.00000 0 23.63904 0.83213 21.21249 0.74671 5.71069 0.40346 5.12455 0.36205 57753.171244 0.000234 0.23277 0.01874 1.00000 0 23.35757 0.81985 20.96594 0.73591 5.43701 0.39388 4.88050 0.35357 57753.171690 0.000211 0.24381 0.01964 1.00000 0 24.74772 0.88666 22.20113 0.79542 6.03377 0.43532 5.41307 0.39054 57753.172118 0.000217 0.24856 0.01996 1.00000 0 23.86107 0.85876 21.41159 0.77060 5.93095 0.42570 5.32215 0.38200 57753.172633 0.000298 0.21717 0.01492 0.99513 0 26.24919 0.76756 23.59125 0.68986 5.70046 0.35443 5.12404 0.31858 57753.231481 0.000231 0.22122 0.01776 1.00000 0 24.36213 0.83116 22.23378 0.75844 5.38951 0.39159 4.91591 0.35714 57753.231950 0.000237 0.23112 0.01829 0.98780 0 23.30945 0.80421 21.29291 0.73461 5.38725 0.38360 4.92368 0.35051 57753.232401 0.000214 0.23181 0.01831 1.00000 0 25.52490 0.88372 23.37514 0.80922 5.91697 0.42016 5.41651 0.38462 57753.232850 0.000234 0.22263 0.01778 1.00000 0 23.76333 0.81386 21.91159 0.75044 5.29032 0.38175 4.87804 0.35200 57753.233310 0.000226 0.23280 0.01877 0.98718 0 23.79416 0.83308 21.93877 0.76811 5.53935 0.40244 5.10744 0.37106 57753.233729 0.000194 0.26935 0.02226 1.00000 0 23.53209 0.89207 21.69824 0.82255 6.33840 0.46554 5.84447 0.42926 57753.234135 0.000211 0.25369 0.02066 1.00000 0 23.03170 0.84741 21.23586 0.78134 5.84287 0.42449 5.38730 0.39139 57753.234583 0.000237 0.23237 0.01803 1.00000 0 23.48980 0.80099 21.65816 0.73853 5.45842 0.38031 5.03276 0.35065 57753.235058 0.000237 0.22865 0.01831 1.00000 0 22.85824 0.79440 21.07414 0.73240 5.22647 0.37714 4.81855 0.34770 57753.235700 0.000405 0.21925 0.01360 0.98571 0 23.97912 0.61716 22.10991 0.56905 5.25742 0.29673 4.84760 0.27360
