/* ** ** 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 57176.434007 0.000428 0.19799 0.01621 0.97297 0 29.97661 0.96825 13.65048 0.43657 5.93502 0.44642 2.69402 0.20053 57176.434878 0.000443 0.21007 0.01701 0.99346 0 29.22712 0.99544 12.15952 0.41239 6.13987 0.45117 2.57539 0.18835 57176.435781 0.000460 0.22163 0.01787 0.98742 0 29.08852 1.00140 11.27422 0.38808 6.44695 0.47012 2.50613 0.18280 57176.436724 0.000483 0.21137 0.01679 0.98802 0 28.41484 0.95234 11.37969 0.38138 6.00615 0.43240 2.40694 0.17322 57176.437659 0.000451 0.20752 0.01651 0.99359 0 30.43213 1.02048 12.27583 0.41176 6.31518 0.45555 2.54931 0.18394 57176.438535 0.000425 0.23988 0.01945 0.95918 0 28.53312 1.00972 11.64162 0.41195 6.84462 0.49927 2.79052 0.20354 57176.439372 0.000411 0.23421 0.01944 0.98592 0 29.18639 1.04032 11.77875 0.41983 6.83571 0.51231 2.75783 0.20668 57176.440202 0.000420 0.24505 0.02003 0.98621 0 27.82648 1.01583 11.17951 0.40799 6.81895 0.49860 2.73748 0.20020 57176.441111 0.000489 0.19523 0.01589 0.98225 0 29.80597 0.96633 11.92870 0.38668 5.81915 0.43433 2.32491 0.17353 57176.442097 0.000498 0.19535 0.01632 0.98837 0 28.33961 0.93431 11.40594 0.37600 5.53623 0.42509 2.22687 0.17083 57176.443032 0.000437 0.23203 0.01874 1.00000 0 28.74185 1.01270 11.24133 0.39591 6.66911 0.48474 2.60464 0.18920 57176.443914 0.000446 0.23515 0.01914 0.97403 0 27.92744 0.98128 11.11871 0.39073 6.56701 0.48213 2.61081 0.19172 57176.445098 0.000738 0.24624 0.01538 0.97647 0 27.78648 0.76665 11.00224 0.30357 6.84216 0.38337 2.71044 0.15187
