- Geomag. fields
- Date:
- 12 Dec 2024 16:36:40
- 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/).

- Title:
- Alma-Ata Station Neutron Monitor Data Service
- Short Name:
- neutrons data
- 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/).

- Title:
- Archive of AGN spectral observations
- Short Name:
- AGN Arch. SSAP
- Date:

- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- The archive of AGN spectral observations is obtained on AZT-8 telescope at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. It represents the result of observations for abot 25 years - from 1970 to 1995. All observations were carried out at AZT-8 (D = 700 mm, F[main] = 2800 mm, F[Cassegrain] = 11000 mm) with a high-power spectrograph. In 1967-68, on the basis of the image intensifier (https://doi.org/10.1080/1055679031000084795a) developed and assembled the spectrograph of the original design in the workshops of the FAI.

- Description:
- The FAI archives's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It is thus the VO's premier way to access public data holdings. Tables exposed through this endpoint include: main from the fai_agn schema, main from the geomagnetic_field schema, main from the grb_photometry schema, obscore from the ivoa schema, main from the maksutov_50_telescope schema, main from the neutrons schema, main from the pulsars schema, main from the schmidt_telescope_lc schema, main from the solar_flux schema, data from the spectra_agn_archive schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.

- Title:
- Galactic X-ray Pulsars
- Short Name:
- FAI xray pulsars
- Date:
- 05 Dec 2024 15:55:05
- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- This catalog contains data on the Galactic population of 82 confirmed X-ray pulsars in high-mass X-ray binary (HMXB) systems, classified into 18 persistent and 64 transient sources. Key parameters include spin periods, spin evolution (local and global trends), orbital periods, X-ray luminosities, magnetic fields, distances, and detailed companion star characteristics. The data have been compiled through cross-matching with recent HMXB catalogs and databases such as Fortin et al. (2023), Neumann et al. (2023), and Krivonos et al. (2022), supplemented with literature and SIMBAD database analysis. The catalog aims to support studies on stellar evolution, accretion processes, and binary dynamics.

- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- This catalog combines photometric and astrometric data from three major sources: the General Catalogue of Variable Stars (GCVS, 2017ARep...61...80S), Gaia DR3, and TESS. It provides detailed information on variable stars, including their coordinates, magnitudes, variability periods, parallaxes, proper motions, spectral classifications, and other physical characteristics. Additionally, the catalog includes computed parameters such as galactocentric distances and model-predicted values for spectral types and variability types for stars with incomplete observational data. The catalog aims to facilitate studies of stellar variability, galactic structure, and stellar evolution.

- Publisher:
- Fesenkov Astrophysical Institute
- Description:
- The “Orbita” Radio Polygon at an altitude of 2750 meters conducts solar radio emission observations using state-of-the-art equipment. This includes instruments for monitoring solar radio flux at frequencies of 1 GHz and 2.8 GHz, as well as the Callisto solar radio spectrograph, which is part of the international e-Callisto network. These tools enable the detection of solar radio bursts of types II, III, IV, and V, and provide valuable insights for forecasting the geo-effectiveness of solar flare activity. The provided dataset consists of daily tables, where each table corresponds to a single observation day. The data includes two columns: - **timestamp**: The time of observation at the detector. - **SFU**: The solar flux unit measurement, representing the intensity of solar radio emission in SFU (Solar Flux Units). The data is collected and provided by the Institute of Ionosphere (https://ionos.kz/).
