Below, post-processing of AUST10 is shown as an aexample Binary files (qcodes and snratio) are in ~/bin Make sure the directory 1234 for AUST10 is in /data/AUSTRAL/aust10 $ cd /data/AUSTRAL/aust10/1234 $ aedit -f alist.ed.out > edit dup SNR > psfile 1234.psfile_rf give full path to 1234.ovex file $ qcodes

Calc/Solve is currently only installed on ops7 in the AuScope control room. To create a database from fourfit output, you should have the /data/ drive on magilla NFS-mounted (sudo mount magilla:/data/ /mnt/magilla/). You should then create a dbedit input file with the following syntax:

Fourfit is the software that performs the multi-band delay fitting to the correlator visibilities. At present, magilla is set up with the latest version and has scripts installed which remove some of the donkey-work in preparing properly fringe-fitted data sets. The following recipe will work for data sets correlated at Curtin.

The full guide to using Calc/Solve is here. The following information describes the process used at Hobart and is aimed at routine processing of post-correlation data. Prepare level 2/3 databases Level 2 databases have an updated clock model applied (using calc11), replacing the model used by the correlator. To generate new databases, edit the

vgosDb vgosDb is now installed on ops7, through the nuSolve package ( slb/nusolve-latest.tar.gz). To build vgosDbMake, it was first necessary to install the HOPS package and then link it in the configure stage. wget ftp://gemini.haystack.mit.edu/pub/hops/hops-3.14-1729.tar.gz tar zxvf hops-3.14-1729.tar.gz cd hops-3.14/ ./configure make sudo make install
