/* ** ** 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 57162.919518 0.000272 0.20167 0.01586 1.00000 0 25.43863 0.81800 20.89592 0.67187 5.13021 0.36816 4.21395 0.30237 57162.920039 0.000249 0.21528 0.01710 1.00000 0 25.59372 0.85749 21.32738 0.71455 5.50990 0.39682 4.59271 0.33076 57162.920545 0.000258 0.20871 0.01658 1.00000 0 25.31939 0.83472 21.20826 0.69915 5.28448 0.38198 4.42510 0.31987 57162.921072 0.000269 0.20457 0.01602 0.98925 0 25.10761 0.81138 21.21356 0.68554 5.13637 0.36627 4.33972 0.30946 57162.921610 0.000269 0.19457 0.01526 0.98925 0 26.36940 0.83303 22.11231 0.69846 5.13066 0.36825 4.30556 0.30894 57162.922165 0.000286 0.18334 0.01421 0.97980 0 26.60781 0.81277 22.40634 0.68445 4.87827 0.34747 4.10711 0.29255 57162.922695 0.000243 0.22829 0.01808 1.00000 0 25.00827 0.85789 20.85169 0.71526 5.70907 0.40763 4.76331 0.34004 57162.923172 0.000234 0.22178 0.01757 0.98765 0 26.71770 0.89779 22.33771 0.75052 5.92547 0.42522 4.95140 0.35529 57162.923679 0.000272 0.18968 0.01474 0.98936 0 27.26495 0.84685 22.59765 0.70184 5.17162 0.36843 4.28376 0.30513 57162.924217 0.000266 0.19465 0.01543 1.00000 0 25.95345 0.83004 21.92798 0.70129 5.05181 0.36653 4.26843 0.30969 57162.924761 0.000278 0.19068 0.01498 1.00000 0 25.52311 0.80208 21.57652 0.67805 4.86686 0.35051 4.11430 0.29631 57162.925296 0.000258 0.21080 0.01656 0.97753 0 25.75474 0.83998 21.66356 0.70653 5.42907 0.38812 4.56610 0.32644 57162.925820 0.000266 0.18935 0.01498 0.98913 0 27.54472 0.86280 22.86210 0.71611 5.21550 0.37884 4.32483 0.31411 57162.926335 0.000249 0.21701 0.01727 0.97674 0 25.78784 0.85807 21.60003 0.71869 5.59614 0.40453 4.68850 0.33891 57162.926833 0.000249 0.22663 0.01787 1.00000 0 24.73074 0.84094 20.57269 0.69952 5.60474 0.39873 4.66578 0.33187 57162.927336 0.000255 0.20705 0.01621 0.97727 0 26.60800 0.85525 22.47152 0.72229 5.50914 0.39329 4.65254 0.33214 57162.927886 0.000295 0.19033 0.01483 0.98039 0 24.83669 0.77030 20.86724 0.64716 4.72705 0.33793 3.97251 0.28400 57162.928453 0.000272 0.19181 0.01491 1.00000 0 26.81088 0.84020 22.25934 0.69752 5.14261 0.36583 4.26869 0.30363 57162.929026 0.000301 0.17804 0.01389 0.98077 0 25.88231 0.77806 21.76520 0.65426 4.60813 0.33188 3.87228 0.27888 57162.929926 0.000599 0.18182 0.01007 0.99034 0 25.32442 0.54862 21.12529 0.45761 4.60441 0.23466 3.83940 0.19567
