So here are a couple: IHW NNSN Part 5 2986 should be 1986 Deep Impact Mission file, mission overview: second paragraph, line 3; " 4 July 4 2005" should be "4 July 2005". line 4 - "The immediately..." should be "They immediately..." Not a typo, but last sentence in para 1 of mission overview: what is "approach solar angle"? Not the same as phase angle, apparently. 9P/Post-encounter Cruise: last sentence: "There are no from..." "There are no data from..."? -Steve _____________________________________________________________________________ From wmo@wansor.jpl.nasa.gov Thu Nov 30 14:45:09 2006 X-Original-To: raugh@icarus.astro.umd.edu Delivered-To: raugh@icarus.astro.umd.edu Delivered-To: raugh@astro.umd.edu From: Bill Owen Reply-To: wmo@jpl.nasa.gov Organization: Jet Propulsion Laboratory To: raugh@astro.umd.edu Subject: PDS review -- typos Date: Thu, 30 Nov 2006 11:45:08 -0800 User-Agent: KMail/1.5.3 MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline X-Status: X-Keywords: X-UID: 198205 Here's my list. I may yet take a closer look at the DI ITS documentation and send along more.

The "queequeg." part of it should be removed, and "queequeg" itself is misspelled in some cases. I'll contact the other people here with the various questions which were raised during the meeting, and I'll forward their answers. It was truly a pleasure to meet you. -- Bill _____________________________________________________________________________ From raugh@astro.umd.edu Mon Dec 4 09:14:02 2006 X-Original-To: raugh@icarus.astro.umd.edu Delivered-To: raugh@icarus.astro.umd.edu Delivered-To: raugh@astro.umd.edu To: raugh@astro.umd.edu, wmo@jpl.nasa.gov Subject: Re: DI nav comments from Bob Werner X-Sun-Charset: US-ASCII Date: Mon, 4 Dec 2006 08:27:43 -0500 (EST) From: raugh@astro.umd.edu (Anne Raugh) Content-Length: 1530 > Anne -- I spoke to Bob Werner yesterday about that document of his, "Deep > Impact Autonav for Anybody."

Look in section 2 of nav_images_report.asc: The raw NAV data files generated from telemetry in the Advanced Multimission Mission Operations Systems (AMMOS) are in a completely different form than the raw science data. Bob Werner at JPL provided the details of the raw format in a document titled ''Deep Impact Autonav for Anybody''. No reference was available; the SDC only received a portion of the document via fax. So the fax in question was sent to Cornell, not to you. Talk to Brian? > > I did point Bob at nav_images_report.asc and I asked him for his > > comments. He clarified it in two places (see attached).

You're most welcome!
