/* ** ** 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 57739.922778 0.000344 0.18546 0.02804 0.94958 0 11.56899 0.68726 5.12187 0.30171 2.14557 0.29826 0.96529 0.13362 57739.923437 0.000315 0.18561 0.03034 0.97248 0 11.82060 0.73626 4.94051 0.30672 2.19399 0.33159 0.90093 0.13515 57739.924195 0.000443 0.16089 0.02508 0.96732 0 12.22301 0.70376 4.14823 0.23879 1.96660 0.28485 0.66270 0.09597 57739.925162 0.000524 0.14413 0.02206 0.95028 0 11.58537 0.62913 3.99097 0.21670 1.66983 0.23898 0.57630 0.08247 57739.926128 0.000443 0.15134 0.02310 0.96078 0 13.26411 0.73305 4.50329 0.24880 2.00741 0.28555 0.67786 0.09643 57739.927022 0.000451 0.15147 0.02354 0.97436 0 12.51925 0.70513 4.26350 0.24004 1.89624 0.27464 0.64526 0.09345 57739.927942 0.000469 0.16084 0.02476 0.94444 0 11.85872 0.67132 4.01662 0.22727 1.90740 0.27300 0.64786 0.09271 57739.928906 0.000495 0.15285 0.02332 0.94737 0 11.96155 0.65948 4.03963 0.22270 1.82829 0.26013 0.61509 0.08750 57739.929832 0.000431 0.19563 0.03022 0.93960 0 11.01625 0.67882 3.70639 0.22838 2.15509 0.30531 0.72233 0.10233 57739.930622 0.000359 0.17082 0.02644 0.95968 0 13.93649 0.83090 4.86976 0.28988 2.38070 0.34009 0.84541 0.12046 57739.931342 0.000362 0.15848 0.02508 0.96000 0 13.76753 0.79372 5.10945 0.29421 2.18186 0.32155 0.80877 0.11899 57739.932158 0.000454 0.19689 0.02626 1.00000 0 11.67379 0.64095 4.43611 0.24353 2.29843 0.27938 0.87383 0.10620
