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/).
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.
The Chandra X-ray Observatory is the U.S. follow-on to the Einstein
Observatory. Chandra was formerly known as AXAF, the Advanced X-ray
Astrophysics Facility, but renamed by NASA in December, 1998.
Originally three instruments and a high-resolution mirror carried in
one spacecraft, the project was reworked in 1992 and 1993. The Chandra
spacecraft carries a high resolution mirror, two imaging detectors,
and two sets of transmission gratings. Important Chandra features are:
an order of magnitude improvement in spatial resolution, good
sensitivity from 0.1 to 10 keV, and the capability for high spectral
resolution observations over most of this range.
This archive collects and re-publishes third-party, mostly amateur,
images of the Gaia astrometry satellite to complemement the Ground Based
Optical Tracking (GBOT) effort.
Until Gaia passivation, there is a temporary upload facility
at https://dc.g-vo.org/citigbot/q/upload/form.

Description:
The Kepler satellite has observed the Galactic center in a campaign
lasting from April until the end of June 2016 (K2/C9). The main
objective of the 99 hours for the microlensing program 097.C-0261(A)
using the ESO VLT Survey Telescope (VST) was to monitor the superstamp
(i.e., the actually downloaded region of K2/C9) in service mode for
improving the event coverage and securing some color-information. Due
to weather conditions, the majority of images were taken in the red
band. These are part of the present release.
The exact pointing strategy was adjusted to cover the superstamp with
6 pointings and to contain as many microlensing events from earlier
seasons as possible. In addition, a two-point dither was requested to
reduce the impact of bad pixels and detector gaps. Consequently, some
events were getting more coverage and have been observed with
different CCDs. The large footprint of roughly 1 square degree and the
complementary weather conditions at Cerro Paranal have lead to the
coverage of 147 events (this resource's events table), but ~60 of
those were already at baseline.
This is a deep optical mosaic of the Fornax cluster’s core, covering
1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an
approximate conversion to V-band magnitudes, the unbinned and binned
mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and
27.8 mag/sq.arcsec, respectively.
