Cycle 7 observation suspention and the delay of the Cycle 8 proposal deadline-COVID-19
As stated on the ALMA Science Portal, Due to the COVID-19 outbreak that has spread to Chile, the ALMA Director has made the decision to suspend science operations with ALMA, effective immediately. The plan is to continue providing data processing,...
- Where can I download the ALMA OT?
- I'm having problems setting up an observation of a line transition that is very close to the edge of a sideband. What should I do?
- How do I deal with targets with unspecified coordinates in the OT?
- How can I reduce my data rates for an observation (and reduce the size of my dataset)?
- What do I do if I get a fatal initialization error when using Web Start?
- I've downloaded the ALMA Proposal Template (LaTeX format). How do I convert it to letter size?
- May I submit an identical proposal to more than one category, e.g. submitting a proposal on distant galaxies both to cosmology and to galaxy categories?
- To which category should I submit a proposal on distant galaxies: "cosmology/high-z" or "Galaxies/Nuclei"?
- What should I do if I have an issue with my proposal assessment?
- May I make changes to my project after the proposal review process?
- Why must I justify data rates higher than 40 MB/s in my Cycle 4 Technical Justification?
- OT will not start due to a security exception
- What should I do if scriptForPI aborts at the importasdm step with error?
- Why do my data products not include all sources/spectral windows/channels for my project?
- On OSX, why is CASA crashing with references to packages that are installed externally to CASA?
- What primary beam does CASA use for ALMA 12-m antennas? And what is the actual ALMA 12-m antenna primary beam, for that matter?
- How do I obtain a file of calibrated visibilities ("measurement set") for ALMA data?
- How does CASA calculate the visibility weights?
- How is noise correlated in CASA when mstransform and tclean are used?
- What should I do if scriptForPI breaks at scriptForImagingPrep step due to an error?
- What spectral resolution will I get for a given channel spacing?
- What is the appropriate acknowledgement to use in our publication?
- How do I link my ALMA user account to my account at a trusted institution?
- What is the astrometric accuracy of ALMA?
- What is a Cycle 7 Solar data issue I should be aware of?
- What translations will be available for user documentation from ALMA?
- I can't seem to register in the Science Portal! What could be the problem?
- How do I track the observational progress of my project?
- Where can I see a list of projects or targets that were observed by ALMA on a given date?
- How can I receive email notification of activity on my ALMA proposals?
