| Staging and subsequent downloading of __**public**__ data always requires an account with LTA user access privileges.

If you do not have an account yet, you can register with "[[https://lofar.astron.nl/useradministration/public/setUpUserAccount.do|Create account]]". LTA access privileges will need to be granted by Science Data Centre Operations (SDCO).

| To stage and retrieve project-related data in the LTA which are __**proprietary**__ you need to have an account in [[https://lofar.astron.nl/mom3|MoM]] that is enabled for the archive and coupled with the projects of interest. To this aim you can request SDCO to be added to the list of co-authors of the project. When you send such a request, you must add the project's PI in cc. After SDCO adds you to the project, you might get an email asking you to set a new password in [[https://webportal.astron.nl/pwm/private/Login|ASTRON Web Applications Password Self Service]]. Please note that this will set a new password not just for the LTA //but for MoM (LOFAR/WSRT) and Northstar as well//. | To stage and retrieve project-related data in the LTA which are __**proprietary**__ you need to have an account in [[https://lofar.astron.nl/mom3|MoM]] that is enabled for the archive and coupled with the projects of interest.

| If you open the file ''srm.txt'' this file contains a list of srm locations which you would feed to ''srmcp''. SRM is a GRID specific protocol that is currently supported for data at the SARA and Jülich locations. It is faster, especially if you have significantly more than 1 Gbit/s bandwidth. It requires a valid [[:public:grid_certificate|GRID certificate]] and installation of the [[:public:grid_srm_software_installation|GRID srm software]]. NB There is an [[:public:srmclientinstallation|alternative installation that does not require root privileges]]. Contact Science Operations and Support if you think you might need a GRID account but it can not be provided by your own institute.
