Since the OT1 process the lifetime expectation has varied considerably. For the purpose of the OT2 process, an indication will be provided in this document. In order to use the most accurate number at hand the final decision about how much observing time to actually allocate in the HOTAC process will only be taken close to the HOTAC meeting (to be held 8-11 November 2011) using all information and analysis then available.

At the moment all available information is being consolidated, and information as appropriate regarding mission lifetime will be prepared and posted on the AO Latest News web page on the HSC website. This page will provide late additions or corrections to the documentation package in general, and should be regularly consulted. The intention is that a note will be posted before the summer holiday season.
