Talk:Very Long Baseline Interferometry
From Wikipedia, the free encyclopedia
The first section could use a rewrite, since it is hard to read for those outside the astronomy field. "Very Long Baseline Interferometry (VLBI) is a type of interferometry in which the data received at each antenna in the array is paired with timing information, usually from a local atomic clock, and then stored for later analysis on magnetic tape or hard disk.". A casual reader may wonder: which antenna, which array? Why is timing so crucial that it is mentioned in the very first sentence?
I'm not an expert in this field, so I hope someone else can do this. I suggest to first tell this has (1) something to do with radioastronomy and (2) involves multiple, geographically seperated, telescopes.

[edit] resolution
changed wikilink resolution to Angular resolution. please change if you know a better place to point artical too.

HALCA is no longer active as of 2005. Refer to http://www.vsop.isas.ac.jp/ for updated information. ChrisTracy (talk) 06:35, 10 December 2007 (UTC)
[edit] Local storage, really?
I'm not involved in the VLA but I have to wonder, in this day of computer networks, if the initial explanation of saving data and atomic clock timing to a tape is perhaps outdated. They must have power supplies and command signals running out to these things, why wouldn't they send timestamped signals back over the network. Also, why would they need an atomic clock at each antenna? Doesn't seem right.
