The IVS Analysis Coordinator's website is backup after a long hiatus. It is my goal to make this a 'one-stop-shop' for matters related to IVS Analysis. It will take some time to reach this goal. If there are items you would like to see on the website please let me know.

Several conventions exist for naming sources,
e.g., the IERS (B1950), IVS, and J2000 conventions.
IVS will now maintain a table of source information that will
provide the names by which each source is known.
This table will also provide source coordinates in J2000.
The table will be available on this web site's
"Data and Information Files" page under the
"Data files for VLBI Data Processing" section, under the
"official IVS source name and translation table"
link.
The initial version is dated 26-Oct-2014.
This table has been developed by and will be maintained by
Karine Le Bail, whose contact information is listed in the file.

Based on discussions at the March 2014 IVS Analysis Workshop,
the Analysis Coordinator is requesting that all software packages
used for IVS add the abilities to a) estimate Earth Rotation parameters (ERP) as
piece-wise linear functions and b) set the epochs of the estimates.
The requested time frame is to add these abilities by the end
of 2014. The Analysis Coordinator also hopes to move towards
reporting ERP at finer intervals. Please see
this message
for more details.
