Coordinates in specdb¶
The algorithms in specdb primarily make use of the SkyCoord class in astropy. For input in scripts and methods, however, most of the routines take a range of formats which are converted by linetools.utils.radec_to_coord to a SkyCoord instance.
Formats¶
Here are the generally allowed formats for input coordinates:
| Style | Type | Example | Comment |
|---|---|---|---|
| J2000 | str | ‘J123411.12+123411.1’ | The ‘J’ is not required |
| colon | str | ‘00:22:33.1,+12:22:33.3’ | The ‘:” are not required |
| radec | tuple | (23.2311, -12.2311) | RA, DEC in deg; units not required |
| coord | SkyCoord |
