Gentlemen,
In the last three weeks I have
received only one e-mail (copied below), from Dick Ferris, with minor errors to
fix in the last draft version. I have fixed these, plus I have added a
page of 'history and acknowlegements' at the beginning which I though
appropriate. The updated version is attached.
Although I set 15 July as the
original deadline for comments, I have been traveling and unable to send a
reminder. In addition, I have made the modifications indicated
above. So I think it appropriate to extend the deadline for comments to
Friday, 21 July. If no substantive objections to the attached version are
heard by 21 July, we shall declare VSI-H version 1.0 to be finalized and ready
for distribution. At that point I will formally notify Richard Schilizzi
(GVWG) and Wolfgang Schleuter (IVS) that the VSI-H version 1.0 specification is
complete and seek their advice for notification and distribution to the wider
VLBI community. Please let me know if this procedure is not satisfactory
for some reason.
Thanks again to everyone.
Regards, Alan

Dick Ferris's e-mail follows:
-
Hi Alan,
I am happy with the recent changes.
-
The break has made it possible to read the document with
fresh eyes.
Consequently here are a few more minor items you may wish to
fix before
going public.
-
p.1 ToC
Entries for 8.2 and 8.3 are transposed. [done - ARW]
-
p.8 8.3 'Speed-up/Slow-down Data Reproduce'
The noun form, 'Reproduction', would sit better with the
rest of the
headings. Change here would also affect the ToC entry above.
[done - ARW]
-
p.8 8.3 "The rates of ...'
'RCLOCK' belongs in this list too. [done - ARW]
-
p.10 10.1 Table 1 'PDATA', p.12 10.4 Table 6 'QDATA'
The serial format for P/QDATA is incompletely specified
(unless it is
somewhere else?). Needs 'one stop bit, no parity'. This is
already the
spec for the control interface in item 1 on p.18. [done -
ARW]
-
pp.10-11 10.1 'Table 2 notes:' ff
The table notes have become separated from their table with
no obvious
link between them. Judicious use of "keep with
next" or some other
formatting device would keep them together. [not done, sorry
- ARW]
-
p.14 12.1.1 First sentence.
Presently missing a preposition. Suggest replacing
"only the use" by
"the use of only". [done - ARW]
-
p.16 12.1.6 Notes:1
Trim the 's' off 'comprises' and append it to 'cable'. [done
- ARW]
-
p.20 14.2 End of second para
'.. as discussed above' is now 'below'. [done - ARW]
-
p.21 14.4 Reference to pulsar timing in Section 10.4.
There's nothing about pulsars in 10.4 now.... [fixed - ARW]
-
p.23 15.1 General fRBSI
Strictly speaking the relation should be
fRBSI<=fDPSCLOCK*2^n, where 2^n
is the optional speedup factor. Perhaps it would be better
if such
information was not repeated in the Glossary anyway. (Also
line
above, fBSI.) [done - ARW]
-
p.26 Figure 2.
'BSIR' is now 'fBSI', 3 places. [done - ARW]
-
p.27 Figure 5.
Caption box needs extending (then recentering) to reveal the
last word,
"Definitions" [done - ARW]
-
p.29 Figure 7.
In the pdf version of this distribution, the vertically
orientated word
"Sample" at time t0 has been "exploded"
off the page. This has not
happened in the .ps file, so is presumably a bug in the V4
version of
Adobe Distiller used to create the pdf. V3 Distiller
successfully
converts the .ps to pdf.
Also the "12" floating above "K" in
"(at CLOCK rate)", 2 places, is
almost lost, as is "Undefined" behind the hashing
in the bottom two
waveforms. These may be effects of the .doc to .pdf
conversion. [done - ARW]

Cheers,
Dick
