/* ** ** 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 56058.154316 0.000411 0.13914 0.01090 0.98592 0 21.89985 0.58709 20.01587 0.53656 3.04718 0.22439 2.78530 0.20512 56058.155205 0.000477 0.11513 0.00879 0.98788 0 22.99640 0.55662 21.11186 0.51100 2.64753 0.19167 2.43060 0.17597 56058.156136 0.000454 0.12311 0.00956 0.98089 0 22.36650 0.56371 20.53640 0.51759 2.75356 0.20235 2.52826 0.18579 56058.157042 0.000451 0.12479 0.00958 0.98718 0 22.30727 0.56589 20.48111 0.51956 2.78370 0.20162 2.55581 0.18511 56058.158275 0.000775 0.13344 0.00750 0.98932 0 22.65481 0.43480 20.80058 0.39922 3.02306 0.15978 2.77563 0.14670 56058.221012 0.000440 0.12525 0.00965 1.00000 0 22.61975 0.57778 20.65827 0.52767 2.83308 0.20582 2.58741 0.18797 56058.221880 0.000428 0.12869 0.00986 0.98649 0 22.91284 0.58795 21.02960 0.53962 2.94869 0.21277 2.70638 0.19528 56058.222745 0.000437 0.11970 0.00920 1.00000 0 23.71125 0.59252 21.75970 0.54375 2.83817 0.20618 2.60454 0.18921 56058.223593 0.000411 0.13964 0.01061 0.99296 0 22.07248 0.58782 20.25653 0.53946 3.08210 0.21941 2.82852 0.20136 56058.224421 0.000417 0.14140 0.01080 1.00000 0 21.36966 0.57532 19.59719 0.52760 3.02176 0.21601 2.77069 0.19807 56058.225595 0.000758 0.14092 0.00784 0.97710 0 22.69425 0.44034 20.78835 0.40335 3.19798 0.16687 2.92921 0.15283
