The DFOSC Spectral Standard Piggyback Survey
Instructions for Danish/DFOSC Observers
The list of optical and UV spectrophotometric
standards that is provided by Jeremy Walsh uses finding charts that are
based on old material from the UK and Oschin Schmidt Telescopes. The standard
stars in this list generally have high proper motions, and now many of the finding
charts are outdated. If you will be observing any of the standards in the list
below, and no-one else has already obtained an image (column 5 of table), then
could we please ask you to help us so that we can in future help you.
- Take a V or R image with the spectrophotometric standard
centred using the full DFOSC field.
- Contact the 2p2 Team coordinator (pager 93-12 or 4217) and inform them
that you have an image. The coordinator will then ftp the image from the ins1d5
workstation and forward it to Jeremy Walsh. There is no need to flat field
the image, but if you can easily do this in the course of your reductions
it would be appreciated.
Instructions for 2p2 Team Coordinators
When an observer obtains an image, please:
- ftp the file down to the 2p2team account, place in the SpecStnd
subdirectory.
- Contact Jeremy Walsh ( jwalsh@eso.org)
and arrange for transfer of the image.
- Update the table below (epu: ~D1p5M/misc/SpecStnds.html)
