"pos.posAng;instr.offset;em" or "pos.posAng;instr.offset", because events are not necessary photons...

this table summarizes the properties of a data set identified for a response data product. This gathers the minimal set of attributes necessary to select a response file ( for example a PSF file within a set of response file) .
the main selection criteria is based on the ids either of the observation , or of the event-list .

will be added in another paragraph about TAP implementation suggestions.

| Discussion: same as for phys.flux.density | ||

| Isn't phys.flux already per unit of surface area ? Has the same dimensionality as phys.flux.density |
There was a problem hiding this comment.
In astronomy, flux, flux density, and flux density surface brightness are all different quantities. Flux is the amount of (energy, particles, ... ) detected from a source per unit time passing through a unit area. The (energy, particles, ...) defines whether it is an energy flux (the default understanding of the term in astronomy unless otherwise specified), particle (most commonly photon) flux, etc. Flux density is the flux per unit in the spectral direction (e.g., per unit frequency, per unit wavelength, per unit energy). Flux density surface brightness is the flux density per unit surface area of the source, if the source is not a point source; so for an extended emission source the surface brightness is typically defined per square arcsec or per square degree.

I don't see instr.sr in the UCD List, but in any case this is nothing to do with the instrument. It's the distribution over the source resolved are that matters.

"Below" can be ambiguous in cases where the quantity varies with the opposite sign of the measure. For example, as surface brightness increases, the measured surface magnitude decreases.

I am trying to fix the workflow.
let's test first that the document is properly generated . then in the next iterations we can fix the other changes proposed in the various commits.
