[Radioig] voltage UCD?

[Mireille LOUYS]

Hi Markus , hi radio astronomers,

I think we can discuss the definition of a new term, if the requirement 
is to label a measurement corresponding to some voltage.

The current procedure for UCD addition is to prepare a short document to 
explain the context for adding a new term.
This can be done in a short file called VEP-UCD.
I have prepared such a file , as included here below.

The first step is to discuss the detailed information of the VEP, and 
the group can finalise the requirement for this UCD :

here is my proposal , to be completed by your inputs as radioastronomers.

----  starts of: VEP-UCD-012_voltage------
Vocabulary extension proposal for UCDs /
Vocabulary: UCDlist 1.6
Author: mireille louys for radio interest group
Date: 2023-03-29

New Term: /phys.voltage/
Action: Addition
Label: Voltage (measured by an instrument)
Prefix: Q
Description:  Voltage quantity

Relationships: can be combined with instr.param for observing configuration
Rationale:
Radio data in raw format can measure a voltage quantity as signal, 
before the data is calibrated.
'phys.voltage' can be used as well to identify a parameter of the 
observation configuration used with an instrument.

Discussion:
To be completed by radio and semantics WG remarks
Pros and cons ...
Other existing ucd terms that can be used instead...

Response: (To be completed by UCD board after discussion)

----  end of VEP-UCD-012_voltage------

When we agree, this can be added on the RequestForModificationPage here:

many thanks for your inputs to finalise this first step.

cheers , Mireille
