| Quick recap | |
| The meeting began with technical setup issues and organizational changes, including the decision to switch to progress reports and postpone certain updates to the next meeting. Roberto presented a comprehensive update on the LOFAR project, covering data management processes, system challenges, and ongoing development efforts to improve user access and data processing capabilities. The team discussed various telescope operations and data management initiatives, including updates on the Effelsberg and apex telescopes, and concluded with plans for upcoming meetings and reports from various institutions. | |
| Next steps | |
| • Roberto to put Lukasz in contact with the right person from the solar community regarding access to Lofar time series data. | |
| • Jérôme to send a slide and link to IRAM's data management system (DMS) for inclusion on the Acme web page. | |
| • Roberto and Jérôme to send a paragraph describing their respective archives and available data products for inclusion on the Acme web page. | |
| • Alex to add information about Effelsberg and APEX telescopes to the Acme web page. | |
| • Andrii to send an announcement with details and link to the indico page for the face-to-face meeting in December in Lausanne. | |
| • Roberto, Jérôme, and Alex to send their presentations to Andrii for uploading to indico. | |
| • Andrii to check and confirm the next regular meeting date for August 29th. | |
| • Andrii to contact Jive for a report at the next meeting. | |
| • BH-DOM team to prepare a report for the next meeting. | |
| Summary | |
| Meeting Updates and Data Access | |
| The meeting began with technical difficulties regarding the Zoom link, which Andrii resolved by introducing a waiting room and assigning Lucas as a co-host to assist with admissions. The group agreed to switch to progress reports for future meetings and planned to hear updates on the standards document and the availability of radio telescope data from Lev, who was tasked with making his data accessible. Due to time constraints, they decided to postpone the Kharkiv report and the European VLBI update to the next meeting, while Roberto was set to present on Lofar. | |
| LOFAR Data Management Update | |
| Roberto presented an update on the Acme Work package related to the Low Frequency Array (LOFAR) project, which involves a massive array of 52 dipole antenna stations distributed across Europe. He explained the data flow process, from signal collection to long-term archiving, highlighting the system's versatility and the challenges of managing vast amounts of data. Roberto also discussed the need to reduce data size, flag interferences, and make the data accessible to users through the Astral Wise interface. He noted that while LOFAR is a valuable instrument, users perceive a high barrier to access due to complex processing and data generation, and efforts are being made to simplify this process. | |
| LTA Product Processing and Development | |
| Roberto discussed the processing and release of advanced products like images, cubes, and catalogs in the LTA, aiming to streamline user tasks and reduce analysis time. He highlighted the need for routine data processing using available computing resources and mentioned ongoing development of a more user-friendly interface, the Astronaut Explorer, which is currently paused due to higher priority tasks but is planned to resume in 2026. Roberto also provided an update on the hours logged for virtual access and development work, which will be used to claim funding allocated for the LTA under Work Package 4 of ACME. | |
| LOFAR Data Visualization Tool Demo | |
| Roberto demonstrated a tool for visualizing and interacting with LOFAR survey data, including the ability to select sky regions and download data products like skymaps. Andrii inquired about extracting flux from sources in the maps, and Roberto confirmed that while this functionality isn't yet available in the system, it's planned for future development. Lukasz expressed interest in accessing time series data from LOFAR for astronomical research, and Roberto offered to connect him with the solar community team who could provide the necessary data access, noting that while the system aims to incorporate all data products, some are currently available through other repositories. | |
| Data Management and Infrastructure Updates | |
| The meeting focused on updates and discussions related to data management systems, archives, and infrastructure safety. Jérôme provided a detailed report on contributions, including data management systems, access statistics, and infrastructure safety, while highlighting the need for virtual access and collaboration tools. Andrii noted that Jérôme was not listed in the Data Archives section of the Acme Web page and suggested adding a link and description of the data products. Roberto discussed the hackme proposal and reset table, while Alex mentioned a report on the apple spured and apex. The conversation ended with a reminder of the remaining time for the next report. | |
| Telescope Data Management Updates | |
| Alex reported on the status and development goals for two telescopes operated by the Max Planck Institute in Bonn: the Effelsberg 100-meter telescope and the apex telescope in the Atacama Desert. The team is working to harmonize and improve access to databases containing raw and calibrated data, with a focus on converting older data into MB. Fits format. They are also discussing server space and web tools with the Max Planck computing and data facility, and have funding to hire a postdoc. Alex mentioned the need for an updated data policy and clarified that "science-ready" data refers to properly calibrated and formatted data available on the Institute's website. | |
| December Meeting and Presentation Plans | |
| The team discussed the upcoming face-to-face meeting in December in Lausanne and confirmed the next regular meeting for August 29th. Andrii will send an announcement with details to the Indigo page, and Jérôme will send presentations to Andrii for upload. The group agreed to include reports from the Kharkiv Radio Astronomy Institute and Jive, with Lukasz's participation to be confirmed due to holiday plans. |
