/* ** ** Swift/XRT hardness ratio for 3C 454.3. ** 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 55177.130968 0.000312 0.38370 0.10483 0.97222 0 1.27914 0.18042 0.94129 0.13255 0.49081 0.11484 0.36699 0.08574 55177.131767 0.000486 0.54559 0.09727 0.98810 0 1.41329 0.15188 1.09405 0.11757 0.77108 0.10969 0.60034 0.08539 55177.132606 0.000353 0.36880 0.09859 0.99180 0 1.12472 0.15906 0.88643 0.12536 0.41479 0.09410 0.32691 0.07416 55177.133500 0.000541 0.56714 0.09845 0.97848 0 1.30708 0.13843 1.03283 0.10939 0.74129 0.10196 0.58564 0.08055 55177.194435 0.000579 0.72229 0.13454 0.96500 0 1.16670 0.14164 0.72606 0.08788 0.84269 0.11906 0.52669 0.07418 55177.195592 0.000579 0.53504 0.11018 0.98000 0 1.23297 0.14941 0.71982 0.08722 0.65969 0.10984 0.38540 0.06410 55177.196744 0.000573 0.69630 0.13235 0.95960 0 1.28196 0.15902 0.74365 0.09225 0.89263 0.12855 0.51901 0.07471 55177.197991 0.000674 0.52513 0.09763 0.96996 0 1.30375 0.14314 0.75925 0.08334 0.68465 0.10273 0.39660 0.05951 55177.199206 0.000541 0.61892 0.11047 0.98396 0 1.58086 0.17758 0.91315 0.10257 0.97843 0.13572 0.56616 0.07851 55177.200210 0.000463 0.40485 0.08615 0.99375 0 1.71882 0.19766 1.00121 0.11509 0.69587 0.12458 0.40601 0.07260
