- | The latest series of HOB experiments are using X-band for observations on the Hobart12-Hobart26 baseline. To get the best sensitivity we are using the DBBC for Hobart26, rather than the mark4 rack. | ||

- | Drudg the experiment file as normal, but please note that you will need to run ''setupxx'' rather than ''setupsx''. Only 8 IFs are being monitored in caltsys (BBCs 1-8, but both USB and LSB channels) and the autocorrelations will appear differently (with the second 8 channels having reversed shapes to the first 8). | ||

The Hobart26m uses the DBBC backend for these experiments rather than the mk5 rack. Unfortunately, the FS only supports controlling one "rack" at a time, so you need to edit configuration files and restart the FS to swap between the backends. There are some instructions included below. | The Hobart26m uses the DBBC backend for these experiments rather than the mk5 rack.
