Next: Solution Up: Simultaneous Phase Retrieval and Previous: Data Model . Following Snyder, Hammoud, and White (1993), we simplify the noise model by defining the modified data . ... In this case, the modified data are approximately equal in distribution to a Poisson process whose mean function is . Therefore, the pseudo-log-likelihood takes the form . ... An explicit, closed form solution to this problem is not known. ...

The wapps in 3 level mode take 100 MHz bw with 64usec sampling and 256 lags. alfa is centred at 1440 Mhz with the 100 Mhz 1390-1490 filter int. The total power was computed and then averaged to .1 seconds. ... Beam 6b is dead and p2030 is adding polA + polB. ... The a2010 data taken on 21sep08 was analyzed to check the stability of all the beams after the bias changes in alfa. ...
