/* ** ** 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 57871.343162 0.000252 0.21604 0.01728 1.00000 0 23.57231 0.78972 20.96485 0.70235 5.09258 0.37000 4.52868 0.32899 57871.343706 0.000292 0.18567 0.01441 0.99010 0 24.39471 0.75009 21.55938 0.66286 4.52944 0.32264 3.99779 0.28476 57871.344250 0.000252 0.19992 0.01572 1.00000 0 25.42574 0.81470 22.77826 0.72982 5.08302 0.36488 4.55551 0.32692 57871.344733 0.000231 0.23321 0.01853 1.00000 0 23.72264 0.82559 21.30989 0.74161 5.53235 0.39506 4.97219 0.35506 57871.345251 0.000286 0.18085 0.01431 0.98990 0 24.99673 0.76440 22.14015 0.67698 4.52072 0.32997 4.00561 0.29243 57871.345809 0.000272 0.19400 0.01497 1.00000 0 25.20130 0.78845 22.35157 0.69927 4.88918 0.34476 4.33821 0.30592 57871.346347 0.000266 0.19005 0.01501 1.00000 0 25.18121 0.79031 22.51374 0.70657 4.78577 0.34684 4.27650 0.30995 57871.346865 0.000252 0.20681 0.01637 0.98851 0 25.02444 0.81728 22.18436 0.72448 5.17520 0.37323 4.59167 0.33115 57871.347383 0.000266 0.20194 0.01614 0.97826 0 23.88804 0.76654 21.48881 0.68955 4.82390 0.35312 4.33940 0.31765 57871.347875 0.000226 0.22999 0.01816 1.00000 0 25.05374 0.85477 22.44867 0.76588 5.76221 0.41036 5.15820 0.36734 57871.348344 0.000243 0.20746 0.01638 1.00000 0 25.45606 0.83789 22.74757 0.74875 5.28122 0.37896 4.71821 0.33859 57871.348818 0.000231 0.23065 0.01831 1.00000 0 24.05258 0.83488 21.54099 0.74769 5.54763 0.39615 4.97219 0.35506 57871.349325 0.000275 0.19818 0.01542 1.00000 0 23.89142 0.75776 21.34766 0.67701 4.73486 0.33639 4.22928 0.30048 57871.349866 0.000266 0.20197 0.01590 1.00000 0 23.70786 0.76845 21.32993 0.69138 4.78819 0.34362 4.30793 0.30915 57871.350395 0.000263 0.19755 0.01545 1.00000 0 24.59363 0.78538 22.12708 0.70662 4.85841 0.34694 4.37116 0.31214 57871.350867 0.000208 0.23888 0.01891 1.00000 0 25.92834 0.91321 23.32703 0.82159 6.19389 0.43903 5.57256 0.39499 57871.351333 0.000258 0.19175 0.01517 1.00000 0 25.79518 0.81675 23.04608 0.72964 4.94613 0.35854 4.42065 0.32040 57871.351859 0.000269 0.18155 0.01421 1.00000 0 26.12626 0.80744 23.50682 0.72648 4.74316 0.34119 4.26760 0.30698 57871.352389 0.000260 0.19857 0.01546 1.00000 0 24.98742 0.79556 22.48199 0.71579 4.96175 0.35253 4.46424 0.31718 57871.352901 0.000252 0.20908 0.01677 0.98851 0 24.29925 0.79790 21.86208 0.71787 5.08060 0.37176 4.57101 0.33448 57871.353413 0.000260 0.20277 0.01591 1.00000 0 24.41707 0.78507 21.96799 0.70632 4.95097 0.35431 4.45437 0.31877 57871.353934 0.000260 0.19636 0.01552 1.00000 0 24.86947 0.79419 22.37570 0.71455 4.88347 0.35302 4.39379 0.31762 57871.354507 0.000312 0.19604 0.01384 1.00000 0 25.77705 0.73861 23.19246 0.66455 5.05340 0.32603 4.54670 0.29334
