Swedish Heterodyne Facility Instrument Science Verification

The Science Verification (SV) observations of the APEX Swedish Heterodyne Facility Instrument were observed in March 2008. ESO requested input from the community by issuing a call for SV projects in February 2008. We received 39 proposals. A selection of the APEX-1 proposals listed below have been observed during the week of joint SV observations in March 2008, and later during the ESO time of period 81. The APEX-3 and APEX-T2 SV projects will be observed later in dynamical scheduling.

SV projects were submitted by all three APEX partners (MPIfR, ESO and Onsala) and the host country Chile. For the joint science verification in March 2008, they were combined in a single pool of observations. The data from all these projects can be downloaded by clicking on the programme ID link on this web page. This will bring you to the archive query form result page of the project, where you will find the raw MBFITS files and a link to a tar file containing the observing logs and merged CLASS files.
