/* ** ** Swift/XRT hardness ratio for Cir X-1. ** 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 57254.199219 0.000523 1.94445 0.50423 0.83333 1 0.73261 0.15646 0.33582 0.07172 1.42453 0.20954 0.64924 0.09551 57254.200556 0.000784 2.02075 0.54449 0.75926 1 0.51150 0.11513 0.23238 0.05229 1.03360 0.15311 0.47240 0.06991 57254.202008 0.000639 1.51618 0.36110 0.77273 1 0.78503 0.14337 0.36174 0.06604 1.19025 0.18195 0.54672 0.08359 57254.203374 0.000668 1.57671 0.40373 0.84783 1 0.66983 0.13829 0.30563 0.06306 1.05613 0.15998 0.48080 0.07283 57254.204782 0.000712 1.98127 0.55791 0.85714 1 0.49113 0.11565 0.22412 0.05278 0.97307 0.15027 0.44306 0.06842 57254.206264 0.000770 1.14281 0.26671 0.77358 1 0.85912 0.15044 0.39282 0.06878 0.98182 0.15148 0.44941 0.06935 57254.208022 0.000988 1.53045 0.31048 0.81791 1 0.75348 0.12224 0.34338 0.05569 1.15316 0.14045 0.52388 0.06380 57254.342692 0.001046 1.26569 0.26231 0.71448 1 0.86596 0.13862 0.38705 0.06192 1.09603 0.14428 0.48958 0.06442
