Processing SMA Data
1.2 m Telescopes
The Radio Telescope Data Center (RTDC) archives, and makes available data from the Submillimeter Array (SMA), the CfA Millimeter-wave Telescope, the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO). We also provide hardware, software tools, and necessary support for the analysis of radio interferometric data from the SMA, JVLA, VLBA, and ALMA.
RTDC machines give users access to all raw SMA science data since 2002, and flux and baseline data going back two years. We also maintain a public data archive containing all SMA data from which visitors can download non-proprietary raw datasets. A subset of calibrated and imaged science data is also available.
The CfA Millimeter-wave telescope archive includes the CO (1-0) spectra from the whole-Galaxy survey presented in Dame, Hartmann & Thaddeus (2001), v-l-b FITS cubes for each survey listed in Table 1 of that paper, plus larger composite cubes and integrated maps.

8 Feb The Karma package is available on RTDC machines. This can be used to make spectra, take 2 and 3D slices, display contours, and analyze expanding shells.
7 Feb The SMA call for proposals for the 2018A semester is open. Find details here.
5 Feb CASA 5.1.2 is available on RTDC computers. This is now aliased to
5 Feb Updates to the web pages are happening today. Expect links to change. UPDATE: Changes are complete.
29 Jan IDL 8.3 is now the default on RTDC machines. You can still access 6.2 by typing
29 Jan See our expanded SMA data FAQ page. Topics include the archive, data format, and data reduction.
26 Jan WIP is now working and exported to all RTDC machines.
17 Jan Miriad-SMA-WB5.0.7 is now available on RTDC machines. In addition to fixes for several data files, the ephemeris tables are updated for solar system objects.
15 Jan AIPS users are reminded to use rglinux10. Please report any issues.
4 Dec Miriad-SMA-WB5.0.6 is available on RTDC machines. This is the default when you source /home/miriad/miriad_WB/automiriad.csh. For pre-'4 chunk SWARM' data check here.
30 Nov There is a new script to convert SMA data from MIR/IDL to UVFITS. Find out more at our updated instructions for opening SMA data with CASA.
19 Oct Unsure which RTDC machine to use for data reduction? See Which machine should I use? for help.
16 Oct A new version of Miriad (Miriad-SMA-WB5.0.5) is available. Known data issues are fixed, and a feature to record the information of mapping the frequency configurations between raw SMA data and Miriad is also implemented.
29 Sep If the baseline solutions need updating, you will now find the correct antenna file provided along with the raw data in the science archive.
29 Sep We bid farewell to our friend and colleague Shoshana Rosenthal who retires this week. We wish her all the best for the future.
19 Sep Proprietary SMA data can now be accessed through our new Proprietary Archive. Available only to PIs or authorized users. You can also request your data be rebinned. More information can be found in the instructions.
14 Sep CASA 5.1.0 is available. Find it here: /opt/casa-release-5.1.0-71.el6/bin/casa.
5 Sep Use our new tool to easily perform unit conversions between frequency, wavelength and spectral resolution.
23 Aug Looking for an easier way to view/filter catalog data? Try TOPCAT (Tool for OPerations on Catalogues And Tables). Available on RTDC machines.
10 Aug The SMA call for proposals is now open. Visit the SMA Observer Center for full details.
4 Aug SMA science data is now at a new location. We are no longer archiving historical non-science data. See here for details.
20 Jul CASA 5.0.0 is installed. Find it here: /opt/casa-release-5.0.0-218.el6/bin/casa. Make sure you are not running CASA on a mounted disk - this will slow it down considerably.
19 Jul When you request SMA data through the Query Form, all sources contained in the raw data will now be listed.
3 Jul Got questions about SMA data? Check out our new FAQ page.
27 Jun CASA 4.7.2 is installed. Find it here: /opt/casa-release-4.7.2-el6/bin/casa.
21 Jun See our updated instructions for converting SMA data to CASA MS format.
14 Jun Summer students - new to Linux or want some new tricks? See our Linux tips page for a list of the most useful commands.
12 Jun For RTDC users: an additional machine, rglinux8 (formerly mayet), is up and running in M-342.
1 Jun A new archive is available here to search for calibration data (pointing/flux/baseline). External users will still have to visit the main Query Form to request the data for download.
12 May For non-proprietary data (since 2007) you can view the observing report from the Query Form results list.
19 Apr Archive search results now report the type of data that are available (raw, calibrated or imaged).
10 Apr Priming data has been removed from the archive.
2 Apr The RTDC computer list is now up to date.
20 Mar All non-proprietary data is available for download from the SMA archive.
14 Mar PI data now binned by a factor of 4 by default. This can be overridden if necessary by clicking a 'Full res.' checkbox on the PI request page.
8 Mar CASA 4.7.1 installed. Find it here: /opt/casa-release-4.7.1-el6/bin/casa
19 Feb Calibrated data is no longer offered as an option to PIs.
