Trying to export at large file but can't seem to get all your records? While we have made every effort to circumvent the timeout issues associated with PHP, depending on the internet connection and your computer speed, you will often not be able to export any file off the Splatalogue homepage larger than about 25MB. The best thing to do is download your file in smaller parts and combine them later. If you are using linux, "cat" is a straightforward way to join separate files together. Again, if you need any help with exporting a large dataset, submit a Helpdesk ticket with Splatalogue through the ALMA Science Portal
Any questions, comments, suggestions or concerns about Splatalogue? We would love to hear from you! Please submit a Helpdesk ticket through the ALMA Science Portal. To reach the Helpdesk, head to the ALMA Science Portal at www.almascience.org and select your preferred ALMA Regional Center (ARC) on the map. You can then reach the Helpdesk by clicking on the link "Helpdesk" that is located on the left panel under "User Services at ARCs." You must first register with the ALMA Science Portal to submit a Helpdesk ticket (it's free!). Once you are registered, log in to the Helpdesk and submit a new ticket. A direct link to the Helpdesk has also been placed under "Navigate" in the top left menu of this page.
The Splatalogue is an attempt to collate, rationalize and extend existing spectroscopic resources for use by the astronomical community. Splatalogue is a transition-resolved compilation of the JPL, CDMS, Lovas/NIST, Frank Lovas' own Spectral Line Atlas of Interstellar Molecules (SLAIM), H, He and C recombination lines, data from the Toyama Microwave Atlas for spectroscopists and astronomers, data from Frank De Lucia's lab at The Ohio State University and and new 13C1-methyl formate data, provided by a group of spectroscopist working on internal rotors (which can be found under the "TopModel" Line List selection). Currently, Splatalogue contains over 5.8 million lines in 1038 individual entries. Open access starts with splatalogue v.1.0 at www.splatalogue.net.
The Splatalogue effort would not be possible without the efforts of laboratories all over the world. Specifically, you will notice in the last column of any search with Splatalogue, the "LineList" where the data originated. For these data, you will need to reference the following:
Specifically, we would like to give special thanks to H. S. P. Müller, Brian Drouin, John Pearson, Frank Lovas and Floris van der Tak for their continued help and support of this effort. Without their efforts and their input, Splatalogue would not be possible.
