Methods Documentation

add(name, physical_type, coord)

Add a new coordinate to the collection.

Parameters:

• name (str) – The name for the coordinate.

• physical_type (str) – An IOVA UCD1+ physical type description for the coordinate. If no matching UCD type exists, this can instead be "custom:xxx", where xxx is an arbitrary string. If not known, can be None.

• coord – The object describing the coordinate value, for example a Quantity or a SkyCoord.

filter_by_physical_type(physical_type)

Filter this object to coordinates with a given physical type.

Parameters:

physical_type (str) – The physical type to filter by.

Returns:

GlobalCoords – A new object storing just the coordinates with the given physical type.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

remove(name)

Remove a coordinate from the collection.

values() → an object providing a view on D's values
