Hi Markus , hi radio astronomers, <br>
<br>
I think we can discuss the definition of a new term, if the
requirement is to label a measurement corresponding to some voltage.
<br>
<br>
The current procedure for UCD addition is to prepare a short
document to explain the context for adding a new term.<br>
This can be done in a short file called VEP-UCD.<br>
I have prepared such a file , as included here below.<br>
<br>
The first step is to discuss the detailed information of the VEP,
and the group can finalise the requirement for this UCD :<br>
<br>
here is my proposal , to be completed by your inputs as
radioastronomers. <br>
<br>
---- starts of: VEP-UCD-012_voltage------<br>
Vocabulary extension proposal for UCDs / <br>
Vocabulary: UCDlist 1.6<br>
Author: mireille louys for radio interest group<br>
Date: 2023-03-29<br>
<br>
New Term: <i>phys.voltage</i><br>
Action: Addition<br>
Label: Voltage (measured by an instrument)<br>
Prefix: Q<br>
Description: Voltage quantity <br>
<br>
Relationships: can be combined with instr.param for observing
configuration<br>
Rationale: <br>
Radio data in raw format can measure a voltage quantity as signal,
before the data is calibrated.<br>
'phys.voltage' can be used as well to identify a parameter of the
observation configuration used with an instrument.<br>
<br>
Discussion:<br>
To be completed by radio and semantics WG remarks<br>
Pros and cons ...<br>
Other existing ucd terms that can be used instead...<br>
<br>
Response: (To be completed by UCD board after discussion)<br>
<br>
---- end of VEP-UCD-012_voltage------<br>
<br>
When we agree, this can be added on the RequestForModificationPage

<br>
many thanks for your inputs to finalise this first step.<br>
<br>
cheers , Mireille<br>

Hm... it would seem nobody has an immediate solution, and reviewing
the current UCD list make me suspect there's nothing remotely
matching -- although I have to admit that I've no clue of PSRFITS...
Does what you'd like to annotate have a complex part because of phase
information in a fourier transform? If so, perhaps stat.fourier
could remotely work?
With that caveat, I suppose the Right Thing™ to do would be to
propose a new UCD. This is less of a hassle than it might sound like

However, I suppose it would be a good idea to discuss the RFM here
first before handing it over to Semantics.
