Information on Service 'FEROS Datalink Service'

Spectra from FEROS spectrograph at La Silla's 1.5m telescope as obtained during commissioning and guaranteed time.

Service Documentation


The FITS RA and DEC header cards contain positions obtained from the telescope guidance system. These positions are frequently off by several arcminutes with respect to the actual object. Therefore, in the metadata table, the positions used for SSA location are obtained from SIMBAD whenever the target names could be resolved.

The nomenclature of objects in the FITS header is somewhat eclectic. For the SSA target name, we use translated names that can be resolved using SIMBAD.

However, there are quite a few names we could no longer make sense of; we marked these in the SSA target names with a tilda (~). For these spectra, the SSA location is constructed from the (flaky) positions in the RA, DEC header cards. Any assistance in figuring out proper designations for the objects observed is appreciated.

This service currently only serves data from the commissioning phase and from guaranteed time on the instrument. Spectra taken in visitor mode may be available from ESO in unreduced form.

If you have reduced spectra obtained with FEROS and would like to publish them, please do not hesitate to contact
