PEN: UDF catalogue 1.2

[Gregory MANTELET]

Dear DAL members,

This is a quick announcement for a minor revision of the
UDF Catalogue Proposed Endorsed Note - version 1.2. This PEN is
now released and may become an Endorsed Note at the next TCG meeting.

So, if this is of some interest for you, please have a review very soon 
as it
may be voted at the next TCG meeting. For questions and comments, Markus 
and Jon
will be glad to collect and answer to them.

For reminder, this note aims to gather ADQL user defined functions 
recommended
by the IVOA. Such functions must be implemented by at least two 
implementations
in order to appear in this note. Those functions are prefixed by `ivo_`.
ADQL/TAP service providers are strongly encouraged to follow the 
definition of
functions listed there for a given feature if already covered by a 
function of
this document. The goal is to prevent the dissemination of variations of 
similar
functions by defining a single function signature and behavior.
Example of UDF already endorsed: `ivo_healpix_index(hpxOrder, long, lat)`.

The previous version was EN-1.1 
<https://www.ivoa.net/documents/udf-catalogue/20231117/index.html> and 
was released on the 10th of October 2023.

In this PEN-1.2 /(see the IVOA doc. version -
https://ivoa.net/documents/udf-catalogue/20240807/ - which matches
the version on GitHub <https://github.com/ivoa-std/udf-catalogue>)/, Jon 
and Markus have added the following functions:

- `ivo_epoch_prop` and `ivo_geom_transform` as astrometry function
- `ivo_simbadpoint` as convenience function
- `ivo_normal_random` as a statistics function
- `ivo_to_jd` and `ivo_to_mjd` as a datetime functions
- `ivo_hms_to_degrees` and `ivo_dms_to_degrees` as a celestial 
conversion functions

Cheers,
Grégory and Joshua
