VISTA SCIENCE ARCHIVE

This form allows you to upload a file of coordinates and cross match the positions with object table(s) in the VSA. Notes on using this form can be found on crossID notes. The supplied file should contain the J2000 RA/Dec coordinates of your objects (one object per line) in decimal degrees or sexagesimal. Values in the file should be separated by spaces or commas, for example the following lines will be parsed correctly

117.000, -25.444
118.123 23.34
11 12 13.4 -30 20 10.0
