/* ** ** 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 56693.522056 0.000407 0.41110 0.11140 1.00000 1 2.96358 0.43054 0.68167 0.09901 1.21832 0.27871 0.27966 0.06398 56693.589395 0.066903 0.79100 0.13935 0.01279 1 2.16485 0.25254 0.49588 0.05784 1.71240 0.22605 0.39178 0.05171 56693.656793 0.000494 0.52814 0.14724 0.94118 1 2.11403 0.34712 0.46968 0.07712 1.11651 0.25156 0.24823 0.05593 56693.657722 0.000436 0.38251 0.10085 0.93333 1 3.33378 0.45628 0.74091 0.10140 1.27521 0.28737 0.28369 0.06392 56693.658623 0.000465 0.45473 0.12565 1.00000 1 2.47211 0.39537 0.54585 0.08730 1.12414 0.25330 0.24823 0.05593 56693.660090 0.001002 0.56391 0.08772 0.99708 1 3.07408 0.29127 0.67913 0.06435 1.73352 0.21388 0.38290 0.04724 56693.722797 0.000450 0.44228 0.11606 0.93548 1 2.85309 0.41575 0.65623 0.09562 1.26186 0.27538 0.28965 0.06321 56693.723582 0.000334 0.64593 0.17917 0.95652 1 2.64915 0.46049 0.61049 0.10611 1.71116 0.36990 0.39487 0.08536 56693.724410 0.000494 0.36464 0.09547 0.97059 1 2.86034 0.38961 0.66682 0.09082 1.04299 0.23323 0.24242 0.05421 56693.725237 0.000334 0.57102 0.16173 1.00000 1 2.64539 0.45984 0.61049 0.10611 1.51057 0.33779 0.34782 0.07778 56693.725920 0.000349 0.51052 0.14144 0.95833 1 2.94060 0.48083 0.68578 0.11214 1.50125 0.33575 0.34782 0.07778 56693.727010 0.000741 0.48344 0.09489 0.98630 1 2.81323 0.32250 0.65171 0.07471 1.36004 0.21667 0.31584 0.05032
