/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 58218.295400 0.000475 0.38067 0.06401 0.97561 0 1.96959 0.17570 1.65165 0.14734 0.74976 0.10687 0.62861 0.08960 58218.296372 0.000498 0.31739 0.05179 0.98837 0 2.23323 0.18176 1.85369 0.15084 0.70880 0.10025 0.58922 0.08333 58218.297365 0.000495 0.40438 0.06849 0.98246 0 1.77267 0.16288 1.46194 0.13434 0.71683 0.10199 0.59307 0.08438 58218.298305 0.000446 0.40665 0.06990 0.96104 0 1.97435 0.18266 1.63484 0.15124 0.80288 0.11632 0.66245 0.09598 58218.299165 0.000414 0.41658 0.06996 0.97203 0 2.12275 0.19411 1.75567 0.16053 0.88429 0.12455 0.73122 0.10300 58218.300050 0.000472 0.32024 0.05366 0.96933 0 2.32818 0.19234 1.92736 0.15925 0.74558 0.10870 0.61716 0.08997 58218.300967 0.000446 0.37714 0.06317 0.98052 0 2.10260 0.18583 1.75528 0.15513 0.79298 0.11282 0.65984 0.09388 58218.301832 0.000420 0.42656 0.07204 0.93103 0 2.08559 0.18977 1.72585 0.15702 0.88963 0.12657 0.73804 0.10500 58218.302715 0.000463 0.34673 0.05868 0.97500 0 2.17405 0.18695 1.80535 0.15524 0.75380 0.10988 0.62507 0.09112 58218.303638 0.000460 0.42785 0.07334 0.99371 0 1.77066 0.16924 1.47107 0.14057 0.75758 0.10780 0.63061 0.08972 58218.304596 0.000498 0.34396 0.05628 0.96512 0 2.10256 0.17306 1.75515 0.14446 0.72319 0.10228 0.60341 0.08534 58218.305672 0.000579 0.42030 0.06150 0.98500 0 1.97303 0.15947 1.64853 0.13325 0.82926 0.10115 0.69359 0.08460
