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.

A Catalog of Galaxies in the Direction of the Perseus Cluster

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.
A all-sky compilation of galactic stellar sources observed for OH
maser emission in the transitions at 1612, 1665, and 1667 MHz. The
database contains OH maser observations selected from the literature .
These observations belong to more than 6000 different objects. The
database consists of three tables: The main table ("masers"),
interferometric followup observations ("maps") and monitoring programs
("monitor").

Description:
This service delivers (most of) the datasets held at
AIASCR VO Services. In addition to the default (nonstandard)
way of just appending accrefs to the get access URL, there is also a
very simple datalink service here that, for each dataset, essentially
just gives the dataset itself and possibly a preview. More advanced
datalink services might be available.
Some datasets may be embargoed, in which case the access yields a 403.
Credentials for individual files may be obtained by contacting the
site operators.
