New parameter(s) for scanning strategy #30

Closed alle-ira closed 4 months ago

alle-ira commented 9 months ago

The introduction of sky_scan_mode in ObsCore Extension is useful to describe the spatial scanning strategies in both interferomentric and SD radio observations. However, its definition does not encompass scan modes in the spectral domain, like frequency switching or spectral scan. A general scan_mode term would need a vocabulary able to represent a) the spatial scanning modes b) the spectral scanning modes, and c) a combination of the two. Alternatively, keeping separate the spatial and spectral scanning modes would require a further parameter (for instance frequency_scan_mode) for the spectral domain alone.

solved with one scan_mode for both spatial and spectral in PR #40
