I'm unaware if this is the correct method and it is only allowed for those who have writing permission in the psql database. --- //[[jtello@iaa.es|Juan Carlos Tello]] 2014/03/07 11:34// If you have a target that you want to change the coordinates (either because the first ones was erroneous or because it is an object like a satellite that requires constant changing and you don't know how to give it the orbital parameters for automatic tracking), then you can access the psql database directly. $ sudo psql stars stars=# UPDATE targets SET tar_ra = 157.246241, tar_dec = 15.760332 WHERE tar_id = 1205; (of course changing the coordinates and target_id as necessary). However it is much easier to do it using JSON using the update_target command: http://serveraddress/jsonapipath/update_target?id=12345&ra=124.43&dec=-23.5
