Telescope (ILT) Foundation. Full LOFAR2.0 roll-out is expected in 2024-2025, followed by early shared-risk observations and full operations thereafter. LOFAR2.0 offers simultaneous low- and high-band observing, increased field-of-view, and various other improvements
to the sensitivity and operation of the telescope. </span><span style="mso-ligatures:none"><o:p></o:p></span></p>

<p class="MsoNormal"><b><span style="font-size:10.5pt;mso-ligatures:none">In-depth justification of all resources required</span></b><span style="font-size:10.5pt;mso-ligatures:none"> is needed: next to observing time, this includes storage and compute capacity,
analysis pipelines, and further support requested of the ILT. The ILT resources will be limited, and additional resources contributed by an L2LP team will be of significant benefit, especially where these can be incorporated into the production data flow for
the L2LP project. A further explanation of the anticipated limitations is given <a href="https://www.lofar.eu/call-for-lofar2-0-large-programmes/#affordable_data_storage"><span style="color:blue">here</span></a>.</span><span style="mso-ligatures:none"><o:p></o:p></span></p>

<p class="MsoNormal"><b><span style="font-size:10.5pt;mso-ligatures:none">A staged approach with initial allocations</span></b><span style="font-size:10.5pt;mso-ligatures:none"> will reflect an affordable best-efforts total resource scenario, as explained <a href="https://www.lofar.eu/call-for-lofar2-0-large-programmes/#review_process"><span style="color:blue">here</span></a>.
As LOFAR2.0 matures, the ILT aims to work with L2LP teams to secure extended capability and capacity for science output/impact over time, allowing phased adjustments to allocations. Also given the anticipated early, shared-risk commissioning stage, a proposed
staged approach to L2LP projects is preferred (e.g., Pilot survey, Phase 1 depth/area, Phase 2 depth/area).</span><span style="mso-ligatures:none"><o:p></o:p></span></p>
