NorthStar is a web-based system for submitting proposals for allocation time for Radio telescopes across Europe. This web-based tool has been baptised as Northstar which stands for : Net-based Observing Request Tool Handling Submissions To ASTRON and RadioNet. text/html 2009-12-02T09:27:25+01:00 Edsard Boelen http://www.astron.nl/northstar/nswiki/doku.php?id=deployment:premade&rev=1259742445&do=diff ASTRON is able to build telescope specific modules for institutes. This page provides a guide how to install a premade version of NorthStar to a machine. First we need to define some variables we will use within this guide Variable Description Example PACKAGE_HOME Root directory of the package /tmp/northstar TOMCAT_HOME Tomcat directory on the machine /opt/jakarta-tomcat-5.5.28/ NORTHSTAR_DB Name of the NorthStar database northstar USER_DB Name of the Useradminsistration database… text/html 2009-11-16T09:34:09+01:00 Edsard Boelen http://www.astron.nl/northstar/nswiki/doku.php?id=deployment:optionsfile&rev=1258360449&do=diff The options file The options.xml is a single xml file which defines mostly content related settings which can be different per category.

They are located in several different directories. Configuration files Here is a short explanation of them: in the (tomcat)/conf directory, there are 2 important files: server.xml contains hostname, security, location of the proposal tool. context.xml can be included into server.xml, contains database info. text/html 2009-10-07T14:42:54+01:00 Edsard Boelen http://www.astron.nl/northstar/nswiki/doku.php?id=misc:calculator&rev=1254919374&do=diff The lofar storage data calculator provides estimates for the amount of data being generated. It can be used to determine the amount of long term storage space needed for an observation. A webservice and a web form is available to directly calculate the values. The formula's here will return the values in bytes. text/html 2009-09-30T16:34:07+01:00 Hanno Holties http://www.astron.nl/northstar/nswiki/doku.php?id=user:faq&rev=1254321247&do=diff Questions Clarification of Early Access and Long Term proposals Early Access are proposals mentioned as Category I in the “Announcement of Opportunity” (ie Commissioning, shared risk, <100hr observations) Long Term are proposals referred to as Category II in the “Announcement of Opportunity” (ie, proposals that target reserved access shares through consortium sponsorship)
