4.1. Archiving Your Data

There are several means for you to obtain a copy of your data once you have finished your observations. The following subsections will describe these methods in detail.

You are requested to make a copy of your data as soon as possible after the observations.

4.1.1. Laptop

You can copy your data to your laptop from the Marsfield SOC. When your laptop is plugged in to a pink cable, you will have to use an SSH tunnel through venice to access the area on kaputar where your data resides.

To set up the SSH tunnel, type the following in a terminal on your computer:

$ ssh -L 2222:kaputar:22

This makes all traffic directed at port 2222 on your computer get transported through venice to kaputar via the usual SSH/SCP port of 22. This tunnel will exist as long as you remain logged into venice in this terminal. Thus to copy your data across, type the following in another terminal:

$ scp -P 2222 “usr123@localhost:/data/ARCHIVE_1/ATCA/archive/*.CX167” .

which would copy all project CX167 data, and where usr123 is your ATNF username.

If you are a CSIRO staff member and can connect your laptop directly to the ATNF network via a blue cable, you may copy the data directly from kaputar:

$ scp “usr123@kaputar:/data/ARCHIVE_1/ATCA/archive/*.CX167” .

4.1.2. Online Archive

Your CABB data will appear on the Australia Telescope Online Archive (ATOA) within a few days of your observations. Using the OPAL account you used to submit your successful proposal, you will have access to your data. Full instructions for how to use the archive interface are available on the website.

4.1.3. Remote Copy

If you are unable to get your data from the ATOA as soon as you would like, then you may get it directly from the disk on kaputar that buffers the data.

To do this, you must set up an SSH tunnel from your local machine to kaputar via the ATNF gateway machine venice. This can be set up with the command:

$ ssh -L 2222:kaputar:22

where usr123 is your ATNF username. This will log you into venice and set up the SSH tunnel, which will remain until you log out. To copy data from kaputar you should go to another terminal and do something like:

$ scp -P 2222 “usr123@localhost:/data/ARCHIVE_1/ATCA/archive/*.CX167” .
