Correlator CDR: Final
Report (doesn't seem to be on ALMAEDM...)
"The committee recommends that the Science IPT clarify the conditions
under which the spectral dynamic range of 40 dB be required. Since
the ALMA correlator is a 2-bit correaltor, the dynamic range can only be
achieved if the narrowband power into the receiver is less than a certain
small fraction of the total receiver power. The Science IPT must quantify
what the maximum total narrowband power is into the receivers, as fraction
of the total receiver noise power."
Some simulations may be needed to determine imaging artifacts
possibly caused by phase and amplitude errors in overlap region of

Plan for further tests of amplitude calibration devices: Jack Welch
tells me that he and Gibson are working on the 3mm horn and expect first
ca. April 2004.
