- What is the procedure in sorting the Spectral Line Picker results by column?
- What are the restrictions on multiple spectral setups within a single science goal?
- What do I do if I try to print my proposal as a PDF and the output is garbled or incomplete?
- How do I change which sideband my spectral windows are placed in?
- How can I estimate the Peak Flux Density per synthesised beam using flux measurements in Jy or K from other observatories?
- 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?
- What is the meaning of the code of an ALMA proposal?
- Why have I not received email notification for some or all of my Proposals?
- If my data were calibrated and imaged in CASA 3.3 and I want to redo it, are there resources to help?
- How can I update Cycle 0 absolute fluxes to the Butler-JPL-Horizons 2012 model standards?
- Will re-reduction improve the Cycle 0 data products provided by the archive?
- The OT instantly fails to startup (commonly EA-ARC issue, with 32-bit JAVA)
- What Cycle 7 proposal issues and clarifications should I be aware of before submitting my proposal?
- Where can I see a list of projects or targets that were observed by ALMA on a given date?
- How can I query the calibrator database that ALMA uses?
- As PI of an ALMA proposal, how can I give others access to the data during the proprietary period?
- How can I see the observation date, the QA0 status, the frequency resolution, the PI name, the largest angular scale, the sensitivity or the QA status of an observation?
- What Calibration and Imaging products will be delivered to me?
- How do I specify antenna locations in simobserve?
- Where can I find data reduction tutorials and recipes using CASA?
- Can I reduce ALMA data in software packages other than CASA, and is there support for that?
- How do I combine multiple executions obtained with a single antenna configuration?
- Does the feathering process for Solar observations differ from that for other observations?
- What is the Atacama Compact Array (ACA)?
- What is the tested capability of ALMA for bandpass calibration precision?
- Can ALMA data be used for studying Earth's atmospheric effects?
- May my proposal include a Co-I whose affiliation is not in any of the ALMA project countries?
- Does the feathering process for Solar observations differ from that for other observations?
- Do I need to specify calibrators for my observation? What are the defaults for Observatory-defined calibration?
- What pwv should I use in my CASA simulations to prepare an ALMA proposal?
- Does the sensitivity calculator account for shadowing?
- Where can I find the configuration files for CASA simulation?
- What is meant by imaging dynamic range?
- I have a professional affiliation with more than one ALMA region. How do I register so I can submit proposals with different affiliations?
- What is the "Choose ARC" entry on the registration page?
- Who answers my helpdesk ticket?
- Where can I find ALMA documentation and manuals?
- How do I update the information for my ALMA Science Portal account?
