JWST Master Class Workshop

JWST Master Class local workshop in Lithuania for Baltic states will be organized on February 20-21, 2020 in Vilnius, Vilnius University.

James Webb Space Telescope is going to be launched soon. The JWST proposal planning tools (APT and ETC) are quite complex. Therefore JWST Master Class will organize a 2-day workshop in Vilnius, Lithuania in order to train participants on how to use these proposal tools and to stimulate proposal ideas. The release date of the JWST Cycle 1 GO (General Observers) Call for Proposals is January 23, 2020 and the deadline for APT (Astronomers Proposal Tool) proposal submission is May 1, 2020.

It is a 2 day workshop where JWST experts will train selected researchers from ESA member states on JWST proposal planning tools, resources and documentation. We plan to have ~20 participants and encourage participation from postdocs and advanced graduate students. Topics of the workshop: JWST mission status and instruments: NIRCam, NIRSpec, NIRISS, MIRI, available proposal tools and end-to-end tools usage, available observing science modes and observing strategies.

Registration. There is no registration fee for this workshop. Registration is now open and will close on Jan 31, 2020.


We acknowledge the grant from the European Social Fund via the Lithuanian Science Council (LMTLT) grant No. 09.3.3-LMT-K-712-01-0103.
