/* ** ** 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 57588.439774 0.001091 0.44107 0.03778 0.96817 0 2.84831 0.13453 2.46606 0.11647 1.25632 0.08978 1.08754 0.07772 57588.441368 0.000503 0.44192 0.05902 0.95977 0 2.57389 0.19125 2.23157 0.16581 1.13744 0.12622 0.98613 0.10943 57588.442172 0.000301 0.41230 0.07092 0.98077 0 2.70107 0.25407 2.34421 0.22050 1.11366 0.16038 0.96642 0.13917 57588.442792 0.000318 0.35050 0.05772 0.97273 0 3.10958 0.26088 2.69617 0.22620 1.08992 0.15443 0.94494 0.13389 57588.443428 0.000318 0.39319 0.06531 0.95455 0 2.88093 0.25622 2.49756 0.22212 1.13276 0.15892 0.98202 0.13777 57588.444753 0.001007 0.34276 0.03102 0.96839 0 3.32040 0.15173 2.88155 0.13167 1.13811 0.08892 0.98767 0.07716 57588.446180 0.000420 0.43142 0.06295 0.94483 0 2.63349 0.20935 2.28580 0.18171 1.13614 0.13900 0.98661 0.12071 57588.446926 0.000327 0.43994 0.07505 0.94690 0 2.43361 0.22909 2.11628 0.19922 1.07064 0.15233 0.93118 0.13248 57588.448388 0.001134 0.41535 0.03542 0.96429 0 2.91767 0.13511 2.52719 0.11702 1.21185 0.08678 1.05122 0.07527 57588.449829 0.000307 0.39629 0.06720 0.96226 0 2.82571 0.25696 2.45154 0.22294 1.11980 0.16029 0.97162 0.13907 57588.450679 0.000544 0.36763 0.04547 0.97340 0 3.10143 0.20018 2.69344 0.17384 1.14017 0.12032 0.99039 0.10451 57588.451527 0.000304 0.35852 0.05857 0.98095 0 3.18599 0.26811 2.76587 0.23276 1.14223 0.15994 0.99194 0.13890 57588.452282 0.000451 0.34768 0.04908 0.98718 0 2.96138 0.21581 2.57169 0.18741 1.02960 0.12449 0.89415 0.10811
