/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 55931.293441 0.001002 0.51028 0.14114 1.00000 1 0.29379 0.04781 0.22627 0.03681 0.14992 0.03353 0.11594 0.02593 55931.295213 0.000770 0.65688 0.18964 0.98113 1 0.30884 0.05639 0.23530 0.04296 0.20287 0.04537 0.15385 0.03440 55931.297218 0.001235 0.37592 0.09846 0.96471 1 0.34136 0.04655 0.25976 0.03542 0.12832 0.02870 0.09756 0.02182 55931.424770 0.126317 0.31949 0.08227 0.01216 1 0.30001 0.03830 0.23556 0.03007 0.09585 0.02144 0.07563 0.01691 55931.552147 0.001060 0.41785 0.11156 0.98630 1 0.33752 0.04924 0.26479 0.03862 0.14103 0.03154 0.11111 0.02485 55931.555067 0.001859 0.33026 0.07452 0.95057 1 0.32828 0.03662 0.25892 0.02888 0.10842 0.02126 0.08548 0.01676 55931.685608 0.001191 0.43732 0.11568 0.98780 1 0.28722 0.04199 0.23450 0.03428 0.12561 0.02769 0.10271 0.02264 55931.688280 0.001482 0.27231 0.06914 1.00000 1 0.36005 0.04330 0.28999 0.03487 0.09805 0.02192 0.07843 0.01754 55931.691185 0.001423 0.31499 0.08156 0.98980 1 0.32222 0.04140 0.26150 0.03360 0.10150 0.02282 0.08206 0.01845 55931.693582 0.000973 0.39868 0.10417 0.98507 1 0.38735 0.05502 0.31618 0.04490 0.15443 0.03387 0.12666 0.02778 55931.695616 0.001060 0.59659 0.17004 0.98630 1 0.22649 0.03968 0.18478 0.03237 0.13512 0.03037 0.11055 0.02485 55931.697533 0.000857 0.49474 0.13658 0.96610 1 0.34483 0.05467 0.28000 0.04439 0.17060 0.03856 0.13894 0.03140 55931.760397 0.062007 0.33356 0.08644 0.02401 1 0.32476 0.04247 0.23642 0.03089 0.10833 0.02423 0.07806 0.01745 55931.824045 0.001641 0.47841 0.11231 0.99280 1 0.27984 0.03761 0.20072 0.02697 0.13388 0.02577 0.09627 0.01853
