/* ** ** 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 56093.101006 0.000527 4.79634 2.62710 0.96703 0 0.06432 0.03216 0.04742 0.02371 0.30850 0.06899 0.22765 0.05090 56093.102366 0.000833 3.33241 1.60498 0.95486 0 0.05977 0.02541 0.04301 0.01828 0.19917 0.04509 0.14406 0.03260 56093.104041 0.000842 9.93575 7.41968 0.95889 0 0.02441 0.01752 0.01783 0.01279 0.24251 0.04991 0.17465 0.03595 56093.368584 0.000744 2.66977 1.18401 0.94942 0 0.07981 0.03017 0.05868 0.02218 0.21306 0.04941 0.15867 0.03679 56093.370441 0.001114 2.21359 0.90702 0.94026 0 0.06716 0.02300 0.04924 0.01686 0.14867 0.03345 0.11006 0.02476 56093.372064 0.000509 4.84601 2.66289 0.95455 0 0.06598 0.03300 0.04857 0.02428 0.31973 0.07279 0.23447 0.05338 56093.373317 0.000744 2.75928 1.21376 0.95720 0 0.07911 0.02990 0.05917 0.02236 0.21829 0.04911 0.16196 0.03643
