- Description:
- AAVSO Photometric All-Sky Survey (APASS), underway since 2010, covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY bandpasses. A northern and a southern site are used, each with twin ASA 20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for all-sky solutions, with typical 0.02mag calibration errors on the bright end. Data Release 10 is a complete reprocessing of all 500K images taken with the system, including hundreds of nights not part of DR9. Sextractor is used for star finding and centroiding; DAOPHOT is used for aperture photometry; the astrometry.net plate-solving library is used for basic astrometry, supplanted with more precise WCS that utilizes knowledge of the optical train distortions. With these changes, DR10 includes many more stars than prior releases. More information is available at http://www.aavso.org/apass.

- Publisher:
- The GAVO DC team
- Description:
- This is a catalog of 5437 morphologically classified sources in the direction of the Perseus galaxy cluster core, among them 496 early-type low-mass galaxy candidates. The catalog is primarily based on V-band imaging data acquired with the William Herschel Telescope. Additionally, we used archival Subaru multiband imaging data in order to measure aperture colors and to perform a morphological classification. The catalog reaches its 50 per cent completeness limit at an absolute V-band luminosity of -12 mag and a V-band surface brightness of 26 mag arcsec^-2 . In addition to the published table, this service also contains cutout images of the objects investigated.

- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- The Alma-Ata Geomagnetic Observatory provides continuous monitoring of Earth's geomagnetic field. Located at 1300 meters above sea level in the foothills of the Tien Shan Mountains, approximately 10 km from Almaty, Kazakhstan, the observatory operates state-of-the-art equipment certified by INTERMAGNET, including the fluxgate magnetometer LEMI-008 and the proton Overhauser magnetometer POS-1. The data service includes: * **Observables**: Three components of the geomagnetic field vector (X, Y, Z) and the total field amplitude (F), measured in nanoteslas (nT). * **Data Resolution**: - XYZ components measured at a 1-second frequency. - F component measured at a 5-second frequency. - Derived minute averages for XYZF components available in real time. - Absolute measurements performed two to three times per week. The service provides open access to minute and hourly data (XYZF components and K-index of geomagnetic activity) through the Institute of Ionosphere's website for data from 2003 onward. Additionally, INTERMAGNET hosts minute variations data since 2004. Data prior to 2003 are available upon request. The data is collected and provided by the Institute of Ionosphere (https://ionos.kz/).

- Alma-Ata Station Neutron Monitor Data Service
- Short Name:

- Date:

- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- The Alma-Ata Cosmic Ray Station operates the 18NM-64 neutron supermonitor at an altitude of 3340 meters above sea level with a geomagnetic cutoff rigidity of 6.7 GeV. The station provides real-time minute-level measurements of cosmic ray intensity and atmospheric pressure, contributing data to the international NMDB network (http://www.nmdb.eu). This service publishes daily tables containing two columns: - **timestamp**: Actual measurement times, ensuring accurate tracking. - **counts/sec**: Cosmic ray intensity in counts per second. The timestamps reflect actual measurement times, ensuring accurate tracking even when delayed data from previous days is incorporated into current files due to communication delays with space stations. The data is collected and provided by the Institute of Ionosphere (https://ionos.kz/).

- 2007-2017 ANTARES search for cosmic neutrino point sources
- Short Name:

- Date:

- Publisher:
- KM3NeT
- Description:
- The ANTARES neutrino telescope aims for the identification of neutrinos from cosmic accelerators. The good visibility towards the Southern sky for neutrino energies below 100 TeV and the good angular resolution for reconstructed events make the telescope excellent to test for the presence of point-like sources, especially of Galactic origin. The data set corresponds to the track sample (muon neutrino candidates) of a study meant to search for a point sources with data collected from January 2007 to December 2017 by the ANTARES neutrino telescope.
