Point coordinates

[Luís Filipe]

Hello,

When i run astrometry, giving the (X,Y) positions of some stars detected in the image, it only uses about 100/250 of them for the analysis, and in the .corr file, it only has the Ra/Dec coordinate of those 100 points.

How can i calculate the coordinates (Ra,Dec) of the other 150 points (X,Y) in the image?

Sorry for bothering,

Luís

Hi,

If you can download & build the astrometry.net code, you can use the "wcs-xy2rd" program to convert between X,Y and RA,DEC coordinates.

cheers,
