maximum_angular_scale min/max #67

Open Bonnarel opened 5 months ago

From Martin Hardcastle, in the context of a SRCnet meeting dedicated to Science Metadata Data Models for Astronomy wher Pat presented CAOM and I presented the Radio extension, I got this remark on the project which makes sense

For consistency one would need a min and max maximum angular scale since that also varies across the bandpass!

@Bonnarel Martin has a point; the maximum angular scale does indeed change with frequency and if the observed fractional bandwidth is large the change can be considerable. The name s_maximum_angular_scale_max sounds a bit awkward, but I guess if we have all three of s_maximum_angular_scale_min (smallest value), s_maximum_angular_scale (typical value) and s_maximum_angular_scale (largest value) it is still clear.

it seems that more generally for the extension of Obscore, all parameters varying with frequency (or energy band in the case of HighEnergy data), should be given with a min and max interval , and a central value with specified frequency ( or energy) .
