The June 30 AIPSLetter for 31DEC14 has been posted on the web page
(and shipped with all MNJs). See links from
http://www.aips.nrao.edu/
There is also a new AIPS Memo 118 on the use of the model fitting tasks
XGAUS, ZEMAN, and RMFIT with a brief section on the model-creating tasks
as well. That is also available via MNJ and the web.
