/* ** ** 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 57567.098698 0.000689 0.56475 0.05037 0.97479 0 3.63318 0.19538 3.04821 0.16391 2.05183 0.14599 1.72222 0.12253 57567.100226 0.000839 0.45681 0.03918 0.96897 0 3.66378 0.17554 3.11238 0.14912 1.67366 0.11907 1.42191 0.10116 57567.101805 0.000741 0.47705 0.04160 0.96875 0 3.93832 0.19551 3.34523 0.16607 1.87876 0.13467 1.59586 0.11439 57567.103336 0.000790 0.48802 0.04231 0.97070 0 3.63982 0.18073 3.09279 0.15357 1.77632 0.12622 1.50944 0.10726 57567.104907 0.000781 0.49631 0.04341 0.97037 0 3.59080 0.18086 3.05090 0.15367 1.78215 0.12743 1.51398 0.10826 57567.106450 0.000761 0.50645 0.04414 0.96578 0 3.65858 0.18461 3.10939 0.15690 1.85288 0.13166 1.57481 0.11190 57567.108452 0.001241 0.47407 0.03320 0.95804 0 3.64963 0.14395 3.10099 0.12231 1.73018 0.10013 1.46988 0.08506
