/* ** ** 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 56753.049135 0.000258 0.16942 0.01338 1.00000 0 29.45006 0.87894 25.96429 0.77491 4.98954 0.36486 4.39863 0.32166 56753.049673 0.000281 0.15960 0.01247 0.98969 0 29.05004 0.83595 25.66928 0.73867 4.63647 0.33678 4.09704 0.29759 56753.050226 0.000272 0.15820 0.01230 1.00000 0 30.20329 0.86785 26.71986 0.76776 4.77802 0.34524 4.22684 0.30542 56753.050749 0.000252 0.17782 0.01391 0.97701 0 29.55473 0.89320 26.14404 0.79012 5.25530 0.37916 4.64887 0.33541 56753.051259 0.000258 0.17135 0.01334 0.98876 0 30.03472 0.89350 26.34664 0.78382 5.14648 0.37037 4.51315 0.32477 56753.051794 0.000278 0.16582 0.01333 0.98958 0 27.70664 0.82628 24.50011 0.73066 4.59435 0.34288 4.06279 0.30320 56753.052402 0.000330 0.13128 0.01007 0.99123 0 30.12503 0.78532 26.63705 0.69440 3.95479 0.28533 3.49694 0.25230 56753.053035 0.000304 0.14499 0.01129 0.98095 0 30.00265 0.82008 26.38022 0.72105 4.35022 0.31723 3.82021 0.27862 56753.053626 0.000286 0.14811 0.01131 1.00000 0 30.82893 0.85232 27.21008 0.75219 4.56607 0.32504 4.02858 0.28678 56753.054169 0.000258 0.17239 0.01381 0.98876 0 29.05364 0.88003 25.55550 0.77401 5.00870 0.37130 4.40685 0.32666 56753.054664 0.000237 0.18304 0.01444 0.98780 0 30.00433 0.92211 26.52963 0.81532 5.49201 0.39892 4.85575 0.35270 56753.055179 0.000278 0.15199 0.01206 0.97917 0 31.04017 0.86960 27.30845 0.76502 4.71788 0.35014 4.14863 0.30791 56753.055712 0.000255 0.16818 0.01316 1.00000 0 30.64805 0.90805 26.71095 0.79137 5.15451 0.37345 4.49226 0.32544 56753.056201 0.000234 0.18524 0.01472 0.98765 0 30.13210 0.93769 26.42084 0.82217 5.58176 0.40824 4.89348 0.35785 56753.056719 0.000284 0.14796 0.01155 0.98980 0 31.20954 0.86680 27.41652 0.76140 4.61768 0.33673 4.05651 0.29586 56753.057254 0.000252 0.16349 0.01257 1.00000 0 31.71165 0.91937 28.03880 0.81289 5.18458 0.36907 4.58425 0.32633 56753.057752 0.000246 0.17076 0.01330 1.00000 0 31.35221 0.93398 27.32905 0.81411 5.35368 0.38525 4.67244 0.33624 56753.058249 0.000252 0.17368 0.01349 0.98851 0 30.41913 0.90384 26.71101 0.79364 5.28327 0.37916 4.64140 0.33314 56753.058779 0.000278 0.15069 0.01173 0.98958 0 31.06967 0.86712 27.47541 0.76681 4.68179 0.34007 4.14017 0.30073 56753.059375 0.000318 0.15489 0.01109 1.00000 0 31.06592 0.81551 27.30514 0.71675 4.81166 0.32049 4.23124 0.28177
