• mar08
  
•  Visiting Committee Commissioning the FPGA spectrometers (.ppt).
• AUSAC  Commissioning the FPGA spectrometers (.ppt).
• spectrometer specs
• how it will be used
• What needs to be done.
  
• feb07 vc meeting: Telescope performance (power point presentation).
• Pointing specs, how we point
• pointing errors
• losing distomats, tiedown cables losing tension
• System performance: gain,tsys,sefd,bw, alfaTsys
  
• may06 FAST presentation: focusing and pointing the telescope.
• feb 05  vcmeeting: Telescope performance (power point presentation).
• pointing: how we do it, model
• distomat failures, tiedown failures, pnt errors when tension lost.
• Pre 2004 gain curves, gain curvature follows shimming error.
• Recent hi freq measurements: cb5000,cbh 7200. Plot gain,sefd vs freq.
• Beamwidth vs wavelength shows underillumination of tertiary by some horns.
  
• mar 03  ausac: Archiving spectral line data at arecibo
• mar 03 galfa meeting: rfi at arecibo (and a little extra).
