Bok Wavelengths are failing for the 600 l/mm grating

We need an arxiv template

Pinging @mcoughlin who may have helped get this rolling along time ago :)

And @mcoughlin -- if you have a successful solution (we can't make one anymore!)
kindly share and I'll do the rest.

@kbwestfall -- which grating is it again?

Just noting here that there has been some off-thread e-mails about this. I would say the provenance of the bok_bc/600 is still unclear. In the short term, we're going to remove this data set from the list that is included in the dev-suite testing. I'll leave the issue open, in case we get a 600 l/mm dataset that we can add to the dev-suite.
