MALT90 Data

MALT90 - year four data release

We are pleased to release the fourth-year data for the Millimetre Astronomy Legacy Team 90GHz (MALT90) survey. This is the final year of data for MALT90.

MALT90 is a large international project aimed at characterizing high-mass dense cores. Exploiting the unique broad frequency range and OTF-mapping capabilities of the Mopra 22-m telescope, MALT90 will be the first systematic survey of several thousand dense cores in the southern sky at this frequency. When complete, MALT90 will be the largest database of molecular line emission toward high-mass star-forming cores.

The fourth data release comprises an additional 100 dense cores mapped during our fourth observing season (Jul 2013). In total, data toward 2012 high-mass dense cores are now available. For each core, the data release includes processed (l,b,v) cubes and (l,b) moment and error maps for all 16 of the emission lines observed.

The data are available through the Australia Telescope Online Archive (ATOA) : http://atoa.atnf.csiro.au/MALT90

MALT90 - year three data release

We are pleased to release the third-year data for the Millimetre Astronomy Legacy Team 90GHz (MALT90) survey.

MALT90 is a large international project aimed at characterizing high-mass dense cores. Exploiting the unique broad frequency range and OTF-mapping capabilities of the Mopra 22-m telescope, MALT90 will be the first systematic survey of several thousand dense cores in the southern sky at this frequency. When complete, MALT90 will be the largest database of molecular line emission toward high-mass star-forming cores.

The third data release comprises an additional 777 dense cores mapped during our third observing season (May - Oct 2012). In total, data toward 1912 high-mass dense cores are now available. For each core, the data release includes processed (l,b,v) cubes and (l,b) moment and error maps for all 16 of the emission lines observed.

Corrected versions of G302.032-00.061 and G311.627+00.290

The datafiles for two source, G302.032-00.061 and G311.627+00.290, both released in year one, originally contained incorrect data. This error was fixed on July 26th, 2012.

The files with these names actually contained data for other MALT90 sources. The FITS headers for this data was correct, so there was a mismatch between the coordinated in the FITS headers and the coordinates you would assume from the source name. The ATOA (Australia Telescope Online Archive) search form uses the file names to find sources near a given coordinate, and thus returned these sources if you searched near the coordinates given in their filenames. The data contained within these misnamed files is duplicated within other MALT90 sources; you should delete the old, misnamed versions of these files.

MALT90 - year two data release

We are pleased to release the second-year data for the Millimetre Astronomy Legacy Team 90GHz (MALT90) survey.

MALT90 is a large international project aimed at characterizing high-mass dense cores. Exploiting the unique broad frequency range and OTF-mapping capabilities of the Mopra 22-m telescope, MALT90 will be the first systematic survey of several thousand dense cores in the southern sky at this frequency. When complete, MALT90 will be the largest database of molecular line emission toward high-mass star-forming cores.

The second data release comprises an additional 636 dense cores mapped during our second observing season (May - Sept 2011). In total, data toward 1135 high-mass dense cores are now available. For each core, the data release includes processed (l,b,v) cubes and (l,b) moment and error maps for all 16 of the emission lines observed.

MALT90 - first year data release

We are pleased to release the first-year data for the Millimetre Astronomy Legacy Team 90GHz (MALT90) survey. MALT90 is a large international project aimed at characterizing high-mass dense cores. Exploiting the unique broad frequency range and fast-mapping capabilities of the Mopra 22-m telescope, MALT90 will be the first systematic survey of several thousand dense cores in the southern sky at this frequency. When complete, MALT90 will be the largest database of molecular line emission toward high-mass star-forming cores.

The current data release comprises the 499 dense cores mapped during our first observing season (June - Sept 2010). For each core, the data release includes processed (l,b,v) cubes and (l,b) moment and error maps for all 16 of the emission lines observed.

The data are available through the Australia Telescope Online Archive (ATOA) : http://atoa.atnf.csiro.au/MALT90
