1 Vocabulary: http://www.ivoa.net/rdf/datalink/core

5 Term: #calibration
6 Action: Modificiation
7 Description: Data products that can be used to remove instrumental
8 signatures from #this. Note that the calibration steps such data
9 products feed have not been applied to #this yet. To link
10 calibration data already reflected in #this, use #progenitor.
11 Used-in: http://dc.g-vo.org/kapteyn/q/dl/dlmeta?ID=ivo%3A//org.gavo.dc/~%3Fkapteyn/data/fits/POT015_000317.fits

13 Term: #bias
14 Action: Modification
15 Description: Data products that can be used to remove detector offset levels
16 from #this.
17
18 Term: #dark
19 Action: Modification
20 Description: Data products that can be used to remove detector dark
21 current from #this.
22
23 Term: #flat
24 Action: Modification
25 Description: Data products that can be used to remove the signature of
26 non-homogeneous detector sensitivity from #this.

28 Rationale:
29 In a discussion on the semantics mailing list (see
30 http://mail.ivoa.net/pipermail/semantics/2020-June/002735.html
31 and follow-ups) it was found that the existing descriptions of
32 #calibration and its narrower terms are ambiguous; "resource used
33 to calibrate" could mean both "resource that has been used" or
34 "resource that can be used". This VEP tries to make it clear that the
35 "has been used" interpretation is for #progenitor, wheras #calibration
36 is for "can be used".
