<p>Dear all,</p>
<p>It seems that the proposed time slots are not ideal for all. We
will try to find a good one, leaving a bit more time to work on
the proposal;)<br>
</p>
<p>I have extended the pool with the 10th, 11th, 12th and 13th of
February: <a href="https://strawpoll.com/e6Z2AWvY6gN"

<p>Dear all,</p>
<p>As discussed during our last meeting, a dedicated discussion is
necessary to provide to the DM WG (and maybe the TCG) a "HEIG
feedback" on the ObsCore extension proposal of Patrick Dowler
(see the attached email).</p>
<p>The purpose of the meeting is to answer to the following
questions:<br>
- Should we approve the scheme of extension of ObsCore for the
radio or the one of insertion of elements into the core ObsCore
DM, in the perspective of our future proposal?<br>
- Are the proposed elements in line with our possible future
proposal?<br>
- AoB</p>
<p>Discussions have been started by email (see exchanges of
François and Ian). We propose to conclude these exchanges with a
remote meeting. Here is a pool to choose the best time slot for
the experts:<br>

<p>I do imagine that Ian, Mathieu and François may desire to
present their thoughts. Any contributions are welcome!</p>
<p>The best,<br>
Bruno<br>

below … a discussion about Obscore on the DM list. We can
discuss next mtg if HE folks interested in this topic are
also on the DM list and then I won’t forward. Since we’re a
new IG … thought it may help. We’ll definitely get Obscore
as a topic of our next mtg.</div>

<div>At the last interOp and while comparing the radio
extension to<br>
CAOM-2.4 and some new features in WD-CAOM-2.5, it became
increasingly<br>
clear that some of the proposed fields for the radio
extension are<br>
more generally applicable and in my opinion should be
promoted to<br>
"core". I kind of volunteered to write down the details
of that, so<br>
here it is that proposal:<br>
<br>
** core **<br>
s_resolution_min<br>
s_resolution_max<br>
s_fov_min<br>
s_fov_max: I still feel the existing s_fov is already
the same as<br>
s_fov_max and not a representative value; it is
nominally the size of<br>
the s_region<br>
t_exp_min<br>
t_exp_max<br>
t_exp_mean: In CAOM exposure is already the mean
exposure time per<br>
pixel and I feel strongly that the existing
ObsCore.t_exptime is<br>
already the same thing (well, it suggests "median
exposure time per<br>
pixel" which I think I may have contributed, but median
breaks down in<br>
some common nearly degenerate cases and is less useful
than mean; we<br>
may need to clarify the definition in ObsCore<br>
f_resolution: absolute spectral resolution is useful,
but this should<br>
be named em_resolution<br>
<br>
** radio extension **<br>
s_maxiumum_angular_scale - I have been convinced by
radio people that<br>
maximum_recoverable_scale is more explicit and a better
term for this<br>
uv_distance_min<br>
uv_distance_max<br>
uv_distribution_ecc<br>
uv_distribution_fill<br>
<br>
Questions:<br>
1. How does this impact the time extension?<br>
2. How does this impact the high energy extension?<br>
<br>
Work:<br>
1. ObsCore needs to be ported to ivoatex (from docx?)
and included in ivoa-std<br>
2. I can set aside time necessary to write the the
changes for WD-ObsCore-1.2<br>
