<p class="MsoNormal" style="margin-left:36.0pt">Dear DAL members,<br>
<br>
This is a quick announcement for a minor revision of the<br>
UDF Catalogue Proposed Endorsed Note - version 1.2. This PEN is<br>
now released and may become an Endorsed Note at the next TCG meeting.<br>
<br>
So, if this is of some interest for you, please have a review very soon as it<br>
may be voted at the next TCG meeting. For questions and comments, Markus and Jon<br>
will be glad to collect and answer to them.<br>
<br>
For reminder, this note aims to gather ADQL user defined functions recommended<br>
by the IVOA. Such functions must be implemented by at least two implementations<br>
in order to appear in this note. Those functions are prefixed by `<span style="font-family:"Courier New"">ivo_</span>`.<br>
ADQL/TAP service providers are strongly encouraged to follow the definition of<br>
functions listed there for a given feature if already covered by a function of<br>
this document. The goal is to prevent the dissemination of variations of similar<br>
functions by defining a single function signature and behavior.<br>
Example of UDF already endorsed: `<span style="font-family:"Courier New"">ivo_healpix_index(hpxOrder, long, lat)</span>`.<br>
<br>
The previous version was <a href="https://www.ivoa.net/documents/udf-catalogue/20231117/index.html">
EN-1.1</a> and was released on the 10th of October 2023.<br>
<br>
In this PEN-1.2 <i>(see the IVOA doc. version -<br>
<a href="https://ivoa.net/documents/udf-catalogue/20240807/">https://ivoa.net/documents/udf-catalogue/20240807/</a> - which matches<br>
<a href="https://github.com/ivoa-std/udf-catalogue">the version on GitHub</a>)</i>, Jon and Markus have added the following functions:<br>
<br>
- `<span style="font-family:"Courier New"">ivo_epoch_prop</span>` and `<span style="font-family:"Courier New"">ivo_geom_transform</span>` as astrometry function<br>
- `<span style="font-family:"Courier New"">ivo_simbadpoint</span>` as convenience function<br>
- `<span style="font-family:"Courier New"">ivo_normal_random</span>` as a statistics function<br>
- `<span style="font-family:"Courier New"">ivo_to_jd</span>` and `<span style="font-family:"Courier New"">ivo_to_mjd</span>` as a datetime functions<br>
- `<span style="font-family:"Courier New"">ivo_hms_to_degrees</span>` and `<span style="font-family:"Courier New"">ivo_dms_to_degrees</span>` as a celestial conversion functions<br>
<br>
Cheers,<br>
Grégory and Joshua <o:p></o:p></p>
