/* ** ** 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 56749.066562 0.000263 0.18828 0.01466 1.00000 0 25.82114 0.79581 23.50313 0.72428 4.86148 0.34753 4.42385 0.31622 56749.067100 0.000275 0.17144 0.01338 1.00000 0 26.92617 0.79784 24.55949 0.72768 4.61616 0.33340 4.20543 0.30376 56749.067601 0.000226 0.20778 0.01621 1.00000 0 27.23693 0.88452 24.91581 0.80908 5.65927 0.40140 5.17464 0.36698 56749.068081 0.000255 0.18815 0.01460 1.00000 0 26.20934 0.81418 24.10678 0.74887 4.93128 0.35054 4.53567 0.32242 56749.068573 0.000237 0.19873 0.01571 1.00000 0 26.48903 0.85142 24.36370 0.78311 5.26429 0.38022 4.84191 0.34972 56749.069053 0.000243 0.18334 0.01437 1.00000 0 27.99636 0.86359 25.75009 0.79430 5.13278 0.36974 4.72096 0.34007 56749.069539 0.000243 0.18540 0.01435 0.98810 0 28.20094 0.86401 25.93864 0.79470 5.22832 0.37165 4.80890 0.34184 56749.070052 0.000269 0.16936 0.01321 0.98925 0 27.53607 0.81120 25.32257 0.74599 4.66357 0.33681 4.28866 0.30973 56749.070572 0.000252 0.17843 0.01390 0.97701 0 28.39386 0.85460 26.11527 0.78602 5.06639 0.36397 4.65982 0.33476 56749.071056 0.000231 0.20860 0.01629 1.00000 0 26.13367 0.85363 24.03747 0.78516 5.45156 0.38655 5.01428 0.35554 56749.071545 0.000252 0.19019 0.01510 0.98851 0 26.18797 0.81642 24.08808 0.75096 4.98057 0.36355 4.58118 0.33440 56749.072034 0.000237 0.19271 0.01534 1.00000 0 27.10705 0.86112 24.93255 0.79204 5.22368 0.38129 4.80465 0.35071 56749.072583 0.000312 0.19698 0.01369 0.99559 0 26.13997 0.73636 24.04260 0.67728 5.14906 0.32720 4.73593 0.30095
