Until that is ready, the Simulator has been hard-wired to produce flat F&#95;nu spectra. Once the library has been delivered, we need to have the Simulator pull spectra from the library.</p> SIM2D-95

If not, can't we complete the book-keeping without waiting for Sean?</p> <p>By "hardwired", I mean that the input spectrum regardless of <tt>objId</tt> is a flat F_nu object. There's no file backing those. I believe the bookkeeping has been taken care of already, and we're just waiting to make the switch once the spectra are delivered.</p> <p>How hard is it to make a file of the proper input format?  Are the arcs and sky also hard-wired (I seem to remember some horrors with the sky).</p> <p>Is there a ticket for Sean to provide the "real" spectra?</p> <p> </p> <p>Here's a simulated galaxy spectrum from <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=sdj" class="user-hover" rel="sdj">Sean Johnson</a> after it's been inserted into the 2D simulator and run all the way through the pipeline.
