/* ** ** 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 57161.788681 0.000298 0.16262 0.01267 1.00000 0 25.75208 0.74605 23.51921 0.68137 4.18770 0.30289 3.82447 0.27662 57161.789228 0.000249 0.20094 0.01565 0.98837 0 25.58864 0.81800 23.37815 0.74733 5.14190 0.36523 4.69785 0.33369 57161.789720 0.000243 0.20228 0.01607 1.00000 0 25.80617 0.83827 23.22526 0.75440 5.22013 0.37836 4.69731 0.34040 57161.790220 0.000258 0.20532 0.01615 0.97753 0 24.54949 0.79374 22.20855 0.71799 5.04042 0.36132 4.55884 0.32676 57161.790715 0.000237 0.21419 0.01679 1.00000 0 24.85453 0.82477 22.73573 0.75446 5.32356 0.37813 4.86973 0.34590 57161.791239 0.000286 0.17598 0.01382 1.00000 0 24.76305 0.74963 22.64783 0.68559 4.35773 0.31580 3.98560 0.28883 57161.791797 0.000272 0.17962 0.01399 0.98936 0 25.94546 0.79025 23.74235 0.72315 4.66044 0.33404 4.26472 0.30567 57161.792338 0.000269 0.19396 0.01510 1.00000 0 24.23238 0.76358 22.17309 0.69869 4.70022 0.33452 4.30077 0.30609 57161.792865 0.000258 0.19406 0.01532 0.98876 0 25.20905 0.79766 23.06666 0.72987 4.89215 0.35384 4.47636 0.32377 57161.793394 0.000272 0.18908 0.01479 1.00000 0 24.59241 0.76540 22.50178 0.70034 4.64987 0.33371 4.25457 0.30534 57161.793889 0.000223 0.21069 0.01656 1.00000 0 26.81385 0.88482 24.53007 0.80946 5.64936 0.40309 5.16842 0.36877 57161.794369 0.000258 0.19478 0.01530 0.97753 0 25.49958 0.80144 23.32498 0.73309 4.96693 0.35762 4.54333 0.32712 57161.794882 0.000255 0.20334 0.01586 0.98864 0 24.85380 0.80043 22.58694 0.72737 5.05388 0.35898 4.58986 0.32602 57161.795400 0.000263 0.18186 0.01417 1.00000 0 26.20181 0.80218 23.97186 0.73391 4.76503 0.34153 4.35845 0.31239 57161.795923 0.000260 0.21939 0.01721 0.98889 0 22.50041 0.75041 20.58641 0.68657 4.93641 0.35044 4.51657 0.32064 57161.796444 0.000260 0.19292 0.01512 0.98889 0 25.28496 0.79382 23.13778 0.72641 4.87797 0.35031 4.46374 0.32056 57161.796953 0.000249 0.18985 0.01494 1.00000 0 26.50001 0.83156 24.25019 0.76096 5.03091 0.36293 4.60376 0.33212 57161.797445 0.000243 0.21669 0.01706 1.00000 0 24.05920 0.80408 22.01005 0.73559 5.21330 0.37176 4.76935 0.34010 57161.797946 0.000258 0.20655 0.01617 0.98876 0 24.24681 0.78445 22.05757 0.71355 5.00813 0.35711 4.55256 0.32464 57161.798426 0.000223 0.22796 0.01814 1.00000 0 24.71984 0.85354 22.60472 0.78049 5.63509 0.40390 5.15089 0.36919 57161.798883 0.000234 0.21125 0.01664 1.00000 0 25.62193 0.84716 23.26983 0.76935 5.41258 0.38702 4.92126 0.35183 57161.799555 0.000437 0.19338 0.01176 1.00000 0 24.64904 0.60543 22.46649 0.55179 4.76661 0.26528 4.34240 0.24167
