/* ** ** 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 60004.194763 0.000446 0.15346 0.01188 0.98052 0 19.13179 0.53638 17.05515 0.47816 2.93589 0.21177 2.61719 0.18879 60004.195597 0.000388 0.17209 0.01322 0.96269 0 20.17817 0.59079 18.05565 0.52864 3.47253 0.24655 3.10733 0.22062 60004.196395 0.000411 0.16363 0.01287 0.97887 0 19.23317 0.55964 17.21465 0.50090 3.14719 0.23007 2.81689 0.20592 60004.197220 0.000414 0.15253 0.01190 0.98601 0 20.55108 0.58045 18.39242 0.51948 3.13460 0.22794 2.80535 0.20399 60004.198018 0.000385 0.16998 0.01319 0.99248 0 19.76816 0.58794 17.69432 0.52626 3.36027 0.24078 3.00772 0.21552 60004.198811 0.000408 0.14949 0.01157 1.00000 0 20.94369 0.58812 18.74892 0.52649 3.13086 0.22584 2.80280 0.20218 60004.199624 0.000405 0.15671 0.01205 0.98571 0 20.61583 0.58588 18.45143 0.52437 3.23064 0.23090 2.89147 0.20666 60004.200550 0.000521 0.12102 0.00934 0.99444 0 20.29779 0.51367 18.16784 0.45977 2.45634 0.17909 2.19861 0.16030 60004.201589 0.000518 0.16182 0.01101 0.98896 0 20.18825 0.51613 18.06815 0.46193 3.26681 0.20596 2.92378 0.18433 60004.261109 0.000425 0.15597 0.01217 0.99320 0 19.97914 0.57139 17.29234 0.49430 3.11614 0.22622 2.69500 0.19561 60004.261971 0.000437 0.14506 0.01127 0.99338 0 20.77706 0.57344 18.10543 0.49971 3.01398 0.21880 2.62313 0.19039 60004.262833 0.000425 0.14868 0.01169 0.99320 0 20.80205 0.58029 17.98235 0.50156 3.09284 0.22746 2.67035 0.19638 60004.263687 0.000428 0.15872 0.01219 1.00000 0 19.82600 0.57200 16.97722 0.48981 3.14681 0.22396 2.69505 0.19181 60004.264688 0.000573 0.15537 0.01042 0.98990 0 20.32041 0.50080 17.45421 0.43020 3.15713 0.19686 2.71379 0.16920
