AstrometricSolution#
- class astropop.astrometry.AstrometricSolution(header, correspondences=None)#
Bases:
object
Store astrometric solution.
- Parameters:
- header: `~astropy.io.fits.Header` (optional)
Astrometric solved fits header. WCS will be extrated from it.
- correspondences: `~astropy.table.Table` (optional)
A table containing the matched correspondences between the (x, y) positions and the matched (ra, dec) catalog coordinates.

Table
between image stars andastrometry.net
index objects.This property is not so smart. It just returns a copy of the table passed as input. If this is an
astrometry.net
correspondences table, it will have the following columns:- field_x and field_y
Image coordinates of each star in the solved image.
- index_x and index_y
X and Y coordinates of matched stars in the index file used to solve the image.
- field_ra and field_dec
Physical RA and DEC solved coordinates of each star in the image.
- index_ra and index_dec
Physical RA and DEC of the matched star in the index file used to solve the image.
