-| July 2018 | 1) All data is now searchable, not only released data or data of projects you're a member of. Note that for downloading data (staging) the proprietary restrictions still apply. \\ 2) All projects can now be selected by all users, not only by project members. This provides the means to filter data based on project.\\ 3) The user interface has been changed to improve user friendliness. Key points are a more intuitive menu structure, improved project selection/deselection and restyling. \\ 4) Implemented cone search algorithm based on the Haversine formula for angular distance calculation. The calculated angular distance to the reference coordinates is now displayed in the search results. \\ 5) Search keys added for "time resolution", "Frequency resolution" and "nr. of subbands per subband group" \\ 6) Search keys removed: "sky model database", strategy name" |+| July 2018 | 1) All data is now searchable, not only released data or data of projects you're a member of.

 The LTA catalogue can be searched directly without needing any account. Access to all projects and search queries will return results of the entire catalogue because metadata are public for all LTA content. The LTA catalogue can be searched directly without needing any account.

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

-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 Science Operations & Support 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 Science Operations and Support 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.
