This fridge must be cycled every day prior to the start of observing. The cycle takes a bit more than 90 min. Before cycling the fridge, please consult with the staff and any other observers about the weather forecast and the observing plan. text/html 2015-09-28T20:50:14+00:00 http://cso.caltech.edu/wiki/cso/instruments/sharcii/data_analysis?rev=1443473414&do=diff SHARC II Data Analysis Overview Like most (if not all!) sub-mm cameras, data from SHARC-II is not trivial to analyze. Each 10 minute file is roughly 30 Mb in size, and many targets (particularly faint point sources) require 3 hours of integration time (that's 0.5 text/html 2015-06-24T06:16:08+00:00 http://cso.caltech.edu/wiki/cso/instruments/sharcii/quickstart?rev=1435126568&do=diff Quick Start Guide This quick guide outlines the steps necessary to start observing with Sharc II or Sharp. The Sharc and Sharp documentation have further details. Please also review the general Introduction to Observing. Remote observers, please review the remote observing policy and instructions.
