/* ** ** 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 55354.911986 0.000593 0.09305 0.01375 0.98537 0 6.01172 0.25854 5.33221 0.22931 0.55937 0.07911 0.49587 0.07013 55354.913071 0.000492 0.11233 0.01714 0.98235 0 5.89279 0.28160 5.24093 0.25045 0.66191 0.09589 0.58829 0.08521 55354.914003 0.000440 0.13038 0.01983 0.97368 0 5.80263 0.29841 5.14460 0.26453 0.75655 0.10827 0.67031 0.09593 55354.914920 0.000477 0.12586 0.01887 0.97576 0 5.60407 0.27944 4.94825 0.24672 0.70530 0.09975 0.62215 0.08799 55354.916040 0.000642 0.11052 0.01457 0.98989 0 5.95158 0.24951 5.27112 0.22097 0.65774 0.08222 0.58344 0.07293 55354.979286 0.000538 0.10175 0.01532 0.99462 0 5.79695 0.26667 5.26535 0.24221 0.58983 0.08454 0.53572 0.07678 55354.980316 0.000492 0.10697 0.01634 0.99412 0 6.09686 0.28790 5.41956 0.25591 0.65219 0.09476 0.58018 0.08429 55354.981366 0.000558 0.10235 0.01561 0.98964 0 5.61471 0.25971 5.02089 0.23222 0.57468 0.08352 0.51335 0.07458 55354.982449 0.000524 0.10854 0.01637 0.98895 0 5.71656 0.26963 5.09949 0.24053 0.62049 0.08891 0.55368 0.07936 55354.983415 0.000437 0.12900 0.01940 0.99338 0 5.77419 0.29506 5.17970 0.26465 0.74485 0.10534 0.66778 0.09444 55354.984408 0.000556 0.09926 0.01472 0.97396 0 6.03555 0.26824 5.37832 0.23900 0.59911 0.08473 0.53565 0.07575 55354.985449 0.000486 0.10946 0.01631 0.97024 0 6.36235 0.29779 5.61405 0.26276 0.69642 0.09849 0.61452 0.08691 55354.986393 0.000457 0.11456 0.01712 0.98101 0 6.37224 0.30706 5.64430 0.27198 0.73000 0.10324 0.64624 0.09139 55354.987333 0.000483 0.11511 0.01722 0.98802 0 5.95051 0.28951 5.26719 0.25625 0.68495 0.09687 0.60707 0.08585 55354.988340 0.000524 0.11552 0.01636 0.99448 0 6.15355 0.28130 5.44914 0.24909 0.71088 0.09528 0.62851 0.08423
