/* ** ** 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 60112.100411 0.000385 0.17205 0.01368 1.00000 0 18.57640 0.55806 17.15764 0.51545 3.19599 0.23523 2.94879 0.21700 60112.101203 0.000408 0.17137 0.01340 0.97163 0 18.25747 0.54027 16.83235 0.49810 3.12884 0.22646 2.88712 0.20894 60112.101985 0.000373 0.17745 0.01405 0.99225 0 18.54517 0.56628 17.24706 0.52664 3.29090 0.24034 3.06054 0.22352 60112.102746 0.000388 0.17728 0.01385 0.98507 0 18.16459 0.54807 16.89331 0.50971 3.22019 0.23215 2.99482 0.21590 60112.103533 0.000399 0.17449 0.01386 1.00000 0 17.50353 0.53410 16.27833 0.49671 3.05414 0.22391 2.84036 0.20823 60112.104366 0.000434 0.15721 0.01257 0.99333 0 17.73695 0.51644 16.49547 0.48029 2.78846 0.20767 2.59328 0.19313 60112.105133 0.000333 0.20873 0.01628 1.00000 0 17.94841 0.59107 16.69208 0.54970 3.74628 0.26490 3.48406 0.24636 60112.105830 0.000365 0.19726 0.01537 1.00000 0 17.34347 0.55666 16.12946 0.51770 3.42111 0.24286 3.18164 0.22586 60112.106591 0.000396 0.17563 0.01362 0.99270 0 18.06670 0.54082 16.80216 0.50297 3.17302 0.22699 2.95093 0.21110 60112.107670 0.000683 0.18925 0.01086 0.99559 0 18.05844 0.41430 16.79437 0.38530 3.41755 0.17978 3.17833 0.16720 60112.163623 0.000373 0.18655 0.01457 0.98450 0 18.54888 0.57598 16.74029 0.51978 3.46038 0.24802 3.12596 0.22402 60112.164408 0.000411 0.16329 0.01278 1.00000 0 18.85765 0.55264 17.16593 0.50310 3.07925 0.22343 2.79931 0.20307 60112.165180 0.000362 0.17058 0.01320 0.98400 0 20.76592 0.61634 19.01694 0.56443 3.54219 0.25319 3.24390 0.23187 60112.166106 0.000564 0.17715 0.01123 0.98974 0 19.43925 0.47837 17.64643 0.43427 3.44362 0.20121 3.12873 0.18282
