Archiving of Magellan Telscope Data at the CFA
The TDC now provides an archive and tape
backup for all CFA and Harvard observers' Magellan raw data here at
CFA, as it has done for the MMT f/5 instrument data.
Since the Internet bandwidth to the Baade and Clay telescopes is too
low to do it directly, the Magellan data usually comes back on the
observer's laptop or other external storage device.
We are asking observers to FTP Magellan raw instrument data to a staging
area for transfer to the archive. The staging area and archive are, of
course, not accessible to anyone except the TDC staff.
Archiving is the only use the TDC will make of the data.
If the data has already been transferred to a disk in the CF domain or
the HEAD domain, and is world-readable (or readable by one of my
groups), just
email Bill Wyatt
the location, and I'll copy it over.
My group list on the CF domain cfyp.cfa.harvard.edu as of this date is:
oir-www tdcin-grp retspec echelle mmti ircam oirsys
oirgroup hectogrp megagrp tdc fastgrp swircgrp keplergrp
I am not a member of any groups (other that my own) in the HEAD domain
federation, but you could request my addition to a group if
you think it more useful.
In general, if it's just as convenient, please use the anonymous FTP
incoming service, where anyone can upload files, but not download
them. I will acknowledge the uploading of
the files when I move them to their final location.
Finally, as a convenience for observers, I have made available two
high-level summaries of all the data. The first is
magellan_pi.db, which gives a count of files for each PI
and instrument, sorted by PI name and then date. The second is
magellan_date.db, which gives a count of files for each PI,
but this time sorted by date and then PI.
Uploading instructions
- cd to your directory holding data.
- ftp cfa-ftp.harvard.edu
- User : ftp
- PW : user@ <-- your name plus the "@" sign
- Then, at the ftp prompt, type:
binary <-- ensure binary mode transfers
prompt <-- turns file-by-file prompting off
cd /incomingonly/Magellan/instr
where instr is one of:
bc imacs ldss magic mike panic
- Assuming your data is divided into one directory per night, e.g.
2006.0524, for each directory type:
mkdir 2006.0524
lcd 2005.0524 <-- your local data directory
cd 2006.0524
