            - review of calibration plan, addressing science loss as a function of the relative and absolute amplitude calibration accuracy of ALMA

            - astronomical source calibration activities that should be started before or during early science operations, whether on other facilities or (when available) ALMA.

            - absolute calibration suggestion from Welch: status of tests

Reading materials
A short summary of the DRSP calibration requirements, with plots, can be found here. See also Chris Carilli's protomemo.  New
Bryan's Calibration Group Web HQ
Bandpass Calibration Memo (Bacmann and Guilloteau) Reviews are in (2 of 3) for this document.
Please view the somewhat drafty Calibration plan.

For 2b ALMA Calibration Source Counts at 250 GHz LAMA No. 805 is available and Mark has circulated a specific draft proposal (an ALMA Memo draft to appear)...  .  New


14:30 pm Discussion


15:00 pm Break


15:15 pm 6.  Total Power and Phase Stability (Wootten)
               - specifications for total power and phase stability for ALMA (Charge 1)

Reading materials
The TP simulations reported last Fall have been updated and issued as ALMA Memo No. 490.  As of about two weeks ago, the stability of independent polarizations spec was reinstated by the Systems group; I will send the text (though it is under discussion).  It will form the basis for Mark to do some further simulations. Phase stability falls into two categories--short term and long term.  For long term, please see LAMA Memo No. 803 "Simulation of Atmospheric Phase Correction Combined With Instrumental Phase Calibration Using Fast Switching"
For short term, this is basically what Larry calls 'decorrelation'.  The WVR addresses timescales longer than 1s.  There is some discussion of this in the calibration Plan.
See also ALMA Technical Requirements and ALMA Scientific Requirements
The System Design Description also has some material of interest on phase stability in particular.  See also the Science IPT's collected Gain Stability Documents.
