21. Science Timeline Realities addressed by JSTAC 06-2010 Science Timeline Realities addressed by JSTAC 06-2010 The JSTAC recommends an Early Release Science Program: “..to obtain images and spectra that would be used to demonstrate key modes of the JWST instruments. The goal of this program is to enable the community to understand the performance of JWST prior to the submission of the first post-launch Cycle 2 proposals that will be submitted just months after the end of commissioning.” “The data… would complement the Early Release Observations (ERO) and the Science Verification (SV) datasets.” “The JSTAC recommends that… data be released both in raw form and with any initial calibrations as soon as possible; the key aspect is speed.”
