aips++ Bulletin #1, April 10/92
Charlottesville, Va
April 10/92
Note:
The aips++ steering committee recently requested a series
of weekly bulletins, briefly stating the group's progress. This
is the first such. People with comments or questions should
direct them through their "nearest" steering committee member.
Members are:
Tim Cornwell, NRAO (Socorro), [email protected]
Geoff Croes, NRAO (Charlottesville) [email protected]
Dick Crutcher, BIMA (U Illinois) [email protected]
Rick Fisher, NRAO (Green Bank) [email protected]
Jan Noordam, NFRA (WSRT Dwingeloo), [email protected]
Ray Norris, CSIRO (Sydney) [email protected]
Dave Shone, NRAL (Jodrell Bank), [email protected]
Ramesh Sinha TIFR (Puna), [email protected]
Tony Willis, DRAO (Penticton BC), [email protected]
1. Notes and memos
A series of aips++ implementation notes and memos has been started.
The distinction is that notes are mostly meant for internal
distribution (although anyone is welcome to read them) and may thus
lack context for outside readers, whereas memos were created with a
wider audience in mind (e.g., domain experts). (Notes may also be used
to "hold" memos which are not yet ready for distribution).
Where possible, all notes and memos will be made available
electronically, although sometimes figures will only be available in
the paper form. Details on paper redistribution will be sent in a
future aips++ bulletin.
Electronic copies of the notes and memos are available via anonymous
ftp from the machine baboon.cv.nrao.edu (192.33.115.103) under the
directory pub/aips++/doc/notes and pub/aips++/doc/memos. File
suffixes are as follows:
.ps - postscript
.tex - plain TeX
.latex - LaTeX
.texi - Texinfo (The GNU projects documentation system)
.text - Plain ASCII text
.dir - A directory that contains multiple files required for
some documents.
A postscript version will generally be made for files which are not
simple ASCII.
Although the list is still being constructed out of past email, disk
files etc, a tentative list of available memos and notes is appended
at the end of this message.
2. Project Book
A decision has been made to create a project book to record the
current state of the project (as opposed to: how we hope things will
be in the future). The general scope of the book is outlined in memo
105, and work on creating it is starting now. Hjellming and
Glendenning will be the initial editors.
The book will be written using Texinfo, and software diagrams will be
produced according to the "Object Modeling Technique" described in the
book "Object-Oriented Modeling and Design" by Rumbaugh, Blaha,
Premerlani, Eddy, and Lorensen; Prentice Hall, 1991.
3. Current Work
Work is proceeding on several fronts in Charlottesville.
The group considering interferometer imaging has made considerable
progress. They have been considering the difficult problems of
mosaicing and isoplanaticity and think they have a design in place
that will work for those problems. Their work is placing constraints
on the telescope model and image structure, some of which are outlined
in Note 132.
The group looking at the telescope model (essentially, calibration)
has been having problems "breaking through" to the next level of
abstraction. While there is a working model for the relation between
the telescope and the data (e.g., Note 130) it may need to be
reexamined after concerns at a more detailed level are examined. The
group is currently looking at data selection, iteration, and
aggregation in a more detailed way.
Work on fundamental libraries is proceeding apace. Some additional
work on hypertext documentation and a simple "keyword=value" input
system is proceeding. System management tools are well advanced. Tools
to provide incremental distribution to remote sites from a central
repository have been created and are being debugged, and a
configuration utility is well under way. A reorganization of the
directory structures was made to allow RCS (Revision Control System)
to be easily replaced with CVS (Concurrent Versions System) at a later
date if concurrent "checkin" becomes desirable.
As scheduled, Bob Sault left the group to return to Australia late
this week. Bob's hard work, past experience, and insightful comments
were all enormously helpful and we hope that the transcontinental
collaboration with Bob will be successful. Thank you Bob.
