Subject: SCIGN site logs

Date: 18 October 1994

Site logs are now available for the Chilao Flats (CHIL) and Holcomb Ridge (HOLC)
stations installed by the USGS as part of the Los Angeles Basin
densification of the Southern California Integrated GPS Network (SCIGN).

The Holcomb Ridge station has been active since 12 August. Chilao Flats
has been active since 2 September. Data are downloaded and stored at the SIO
archive in the same manner as PGGA stations.  Data from these sites are
incorporated into the daily analysis at SIO which includes IGS,
SCIGN (PGGA/DGGA), and BARD stations.

Site logs for these and all other active SCIGN stations are available from:

(1) the Scripps Orbit and Permanent Array (SOPAC) Mosaic, accessible through 
the SIO/IGPP Home Page:

       http://igpp.ucsd.edu/
