Is there a way to generate a data file that lists the objects and named stars that are labelled on the annotated graphic file? The graphic with circles and notations is helpful, but I would also like to have a file that lists the x, y pixel coordinates from the original photo that correspond to each labelled object and star, along with the label... something like:
172  621   HD14580
361  443   NGC884 / Double Cluster
(etc...)

We have an api that we use for the Flickr bot that has this information. Not sure if this is exactly what you're looking for though.

Using the job id, you can get that list as a JSON literal, eg

http://nova.astrometry.net/api/jobs/803513/annotations/

yields

{"annotations": [
{"radius": 0.0, "type": "hd", "names": ["HD 85743"], "pixelx": 918.410173968801, "pixely": 524.8937593698096},
{"radius": 0.0, "type": "hd", "names": ["HD 85458"], "pixelx": 863.08641924214, "pixely": 1147.7544310460146},
{"radius": 0.0, "type": "hd", "names": ["HD 85534"], "pixelx": 1510.8754971071544, "pixely": 1044.362081651932},
{"radius": 765.05887958557491, "type": "ngc", "names": ["NGC 3031"], "pixelx": 1459.5382236707762, "pixely": 1041.2017278957865}
]}

That work for you?
