---+ Request for Modification (RFM) for the UCD vocabulary towards UCDList v1.7

This page summarises the steps for Modifications and Updates proposed in the [[https://www.ivoa.net/documents/UCDlistMaintenance/index.html][UCD List Maintenance]] recommendation. The UCDListMaintenancePage summarises the past and current RFMs.

The third (on going) iteration for the Request for modifications of UCD terms is summarized in the following content.

These terms are submitted for evaluation to the UCD science committee (see details in the Maintenance Specification document).

---+ UCDList v1.7 Request For Modifications, from Jan 2025 to now

---++ Proposed RFMs
---

<span style="color: mediumvioletred;">***** currently in construction <b>***</b></span>

Still in discussion from RFM 1.6
---+++ Proposal from MarkusDemleitner & BaptisteCecconi ( [[https://voparis-gitlab.obspm.fr/vespa/ivoa-standards/semantics/vep-ucd/-/blob/master/VEP-UCD-005.txt][VEP-UCD-005]], initially in [[UCDList_1-4_RFM][UCDList 1.4 RFM]])

   * *Proposed term*: stat.histogram
   * *Proposed description*: An array-like object with counts or ratios in bins
   * *Prefix*: P
   * *Rationale*:
   * *Used-in*:
   * *Discussion*: See [[https://voparis-gitlab.obspm.fr/vespa/ivoa-standards/semantics/vep-ucd/-/blob/master/VEP-UCD-005.txt][VEP-UCD-005]], and [[UCDList_1-4_RFM][UCDList 1.4 RFM]] for the detailed discussion.
*Sci-UCD Further Discussion*: The same discussion as that of *pos.moc* applies for the use cases. Depending on how what is tagged, P or S flag should be used, and a specific *dataproduct_type* may also be needed to advertise a product in an ObsTAP or EPN-TAP table.

BC [2023-06-22]: what about using `stat.distribution` which would be more generic (with possible child `stat.distribution.cumulative` or `stat.distribution.histogram`) ?

*BC [2024-03-21]: pending , needs more discussion*

<br /><br />
---+++ Proposal from M.Louys ( [[https://voparis-gitlab.obspm.fr/vespa/ivoa-standards/semantics/vep-ucd/-/blob/master/VEP-UCD-015.txt][VEP-UCD-015]])

   * *Proposed term*: phys.pulseHeight or phys.pulse.amplitude
   * *Proposed description*: Amplitude measured by a pulse analyser after a particle or radiation detector (photon, gamma ray, ...).
   * *Prefix*: Q
   * *Description*: In event-list data product obtained in X-ray or Gamma-ray, the need to characterise the raw measure provided by the detector has appeared. A similar requirement was formulated for radio data as well.
   * *Rationale*: This term would be useful to refer to raw data coming out of a detector and not calibrated yet. The need for such a term was mentionned during the preparation of the IVOA Note "VO Data discovery for High Energy data sets".
   * *Used-in*: Chandra event-list, CTA event-list before calibration.
   * *Discussion*:
      * There may be an overlap with the proposal for "phys.adu" in VEP-UCD-14.txt. To be discussed.
      * [2024-03-21] Existing UCD for pulse: "src.var.pulse" and for amplitude: "src.var.amplitude" (but with E prefix, which should be changed Q to have this word applied to any other primary word)
   * *BC [2024-03-21]: Proposed change*: "src.var.amplitude" prefix set to "Q".
      * proposed solution: * "src.var.amplitude;src.var.pulse;stat.uncalib"
   * ML [2025-02-12] currently discussed again with the HEIG interest Group.
---++ Proposed RFMs - modification suggestions for planetary science
---++++ Proposals from J. Berthier , IMCCE, Paris Observatory

List of terms and concepts to cover (open for discussion) : [[%ATTACHURL%/ucd_RFM_SolarSystem_JB.pdf][UCDs Requests for Planetary data]]

See [[https://voparis-gitlab.obspm.fr/vespa/ivoa-standards/semantics/vep-ucd/-/blob/master/VEP-UCD-016.txt][VEP-UCD-016]] document for discussions.

Generic comment: We need "Used-in" sections to be filled.

*Discussion*:
   * ML [2025-02-12] pending , need a new iteration for clarification of requested terms .
