There are two main ways to start working with VOSA:
- Uploading a VOSA-format input file with your data (or selecting a previously uploaded one).
VOSA is mainly designed to work with several objects at the same time so that the same or equivalent operations are performed on all the objects. The information about these objects (and optionally, user photometry data for them) must be uploaded by the user in an input ascii file with an special format.
Please, read carefully how to write an input file in VOSA-format.
- Making a simple search for a single object giving its coordinates.
Using these coordinates VOSA builds an input file and uploads it automatically to the application.
And, at any time, you can select a previously uploaded file and continue with it in the same point where you left the work.
Below you can see details about these three options.
