Description:<BR>
The above paper describes the compilation of the second Kiso UV-Excess
galaxies survey as KUG2 catalogue. The result is shown in VII/994. The first
survey catalogue KUG1 is shown in VII/179A.
As is described in the paper, there are some differences between KUG1 and
KUG2, e.g. in photographic plates used and the observation condition in the
surveys, such as emulsions, exposures or seeing sizes. The homogeneity of
these KUG surveys is rather low, but their catalogues form a somewhat large
collection of UV-excess/blue galaxies. In these circumstances, we intend to
merge both catalogues, upon requests from investigators working in follow-up
observations of these galaxies.
In the process of catalogue merging, we met a systematic difference between
the first (KUG1) and the second (KUG2) surveys in overall properties of
objects, such as brightness, degree of UV-excess and morphological type.
This mainly originates from differences in the observation condition and
personal errors in the survey. We scrutinize and discuss those differences
and errors, and finally merge into a comprehensive catalogue of KUGs
(KUG2000) in the machine-readable form including near ten thousand
UV-excess galaxies.

Description:
The VSOP (VLBI Space Observatory Programme) mission was led by the Institute of Space and Astronautical Science, in collaboration with the National Astronomical Observatory of Japan with international collaboration with NSAS, CSA, JIVE and the world radio telescopes in 14 countries.
This mission provided a dedicated space radio telescope "HALCA" launched in February 1997, and carried out high-resolution observations at 1.6, 5.0, and 22 GHz with ground radio observatories to perform Very Long Baseline Interferometry (VLBI) on baselines of up to 2.6 Earth diameters. The observations are continued till 2003, and HALCA finished its operation in 2005.
This table records high-level information for the observations obtained with Hitomi. Hitomi was equipped with four different instruments that together cover a wide energy range 0.3-600 keV. Data were collected from six celestial objects (Perseus, N132D, IGR_J16318-4848, RXJ1856.5-3754, G21.5-0.9, and Crab) as well as black sky for a total of about one month of data in 2016.
IRSF (InfraRed Survey Facility) is located at Suhterland, South Africa and the survey project started since Nov. 2000 in the near infrared (J, H, Ks) bands. The facility (SIRIUS camera and 1.4-m IR telescope) is easy both for operation and data-reduction, owing to its simplicity. The instrument has been producing numerous scientific data every clear night for the last four and half years under friendly collaboration between Nagoya Univ-Kyoto Univ-NAOJ (Japan) and SAAO (South Africa).
IThe Japanese satellite-borne infrared telescope, the Infrared Telescope in Space (IRTS), surveyed about 7 per-cent of the entire sky in the infrared wavelengths from 1.4 to 700 um. The IRTS consists of a 15 cm telescope cooled with superfluid liquid helium, and is installed on board the Space Flyer Unit (SFU) spacecraft. The SFU was launched on 1995 March 18 UT. The sky survey by the IRTS started on March 29 UT, and was completed on April 25 UT after exhausting its liquid helium. The four focal-plane instruments were on board.
The Mid-Infrared Spectrometer (MIRS) covered 4.5 to 11.7 um by 32 spectral channels with the resolution of Δλ = 0.23-0.36 um. The MIRS point source catalog contains spectra of 536 sources. Many of the detected sources are mas-losing stars. A few HII regions and one asteroid 01 Ceres are included.

The Near-Infrared Spectrometer (NIRS) covered 1.4 to 4.0 μm by 24 spectral channels with the resolution of Δλ = 0.13 μm. The complete level of the catalog is 10?20 Jy for the entire wavelength range. The NIRS point source catalog contains spectra of 14,223 sources in which 4,002 sources are in good quality. Late-type stars, normal stars, and other red objects are included.
