This set of star charts shows the whole starry skies visible in different seasons in the 40 ° north latitude region. The outer circle of the star map is marked with East, West, North and south directions. The innermost circle is the horizon of the observation site, and the center of the star map is the zenith of the observation site. When using, you can lift the star map so that the directions marked on the map are consistent with the actual directions. Then you can follow the map and learn to identify the constellations step by step starting from recognizing the bright stars. Stars brighter than 4 magnitude and a small number of stars with brightness of 5 magnitude are depicted in the figure. Bright stars are marked with Chinese star names. Some well-known deep space objects are also reflected.

Gaia Data Release 3

Publish Time: 2022-06-13

DOI: 10.12149/102020

Gaia space telescope is a very important project of the European Space Agency and is a follow-up project of the Hipparcos space telescope. It was launched in December 2013, arrived at the second Lagrange point of the Earth Moon system a few weeks later, and began a five-year sky survey mission in mid August 2014. Its main goal is to measure the three-dimensional space and three-dimensional velocity distribution of stars to determine their astrophysical properties, such as surface gravity and effective temperature, to describe and understand the formation, structure， history and evolution of the Milky Way. On 13 June 2022, Gaia Data Release 3(Gaia DR3) is released. The Gaia Early Data Release 3 (Gaia EDR3) released in October 2021 mainly contains the position, magnitude, proper motion and parallax of 1.5 billion stars, as well as the pseudo color information of some stars with poor photometric quality. Gaia DR3 neither contains new astrometry nor new photometric calibrations, thus, the photometry and astrometry data are common for DR3 and EDR3. However, DR3 has added more data on astrophysical parameters, such as spectral related parameter data, variable star list, and data on celestial bodies in the solar system. For the first time, there is data on the source of expansion (such as galaxies and quasars).

CSTR: 11379.11.100448

LAMOST Data Release 5, covering ∼17,000 sq. deg from −10 to 80 deg in declination, contains 9 millions co-added low resolution spectra of celestial objects, each spectrum combined from repeat exposure of two to tens of times during Oct 2011 to Jun 2017. In this data release, the spectra of individual exposures for all the objects in LAMOST Data Release 5 are presented. For each spectrum, equivalent width of 60 lines from 11 different elements are calculated with a new method combining the actual line core and fitted line wings. For stars earlier than F type, the Balmer lines are fitted with both emission and absorption profiles once two components are detected. Radial velocity of each individual exposure is measured by minimizing χ2 between the spectrum and its best template. Database for equivalent widths of spectral lines and radial velocities of individual spectra are available online. For stars observed in the same day and with signal-to-noise ratio higher than 20, the radial velocity uncertainty is below 5km/s, and increase to 10km/s for stars observed in different nights.

The Gaia + PanSTARRS1 (PS1) + Sloan Digital Sky Survey (SDSS) + Two Micron All-Sky Survey (2MASS) (GPS1) catalog was released in 2017. It delivered precise proper motions for around 350 million sources down to a magnitude of r ~ 20 mag. In this release, the author presents GPS1+, the extension GPS1 catalog down to r ~ 22.5 mag, based on Gaia data release 2 (DR2), PS1, SDSS, and 2MASS astrometry. GPS1+ totally provides proper motions for ∼400 million sources with a characteristic systematic error of less than 0.1 mas yr−1. This catalog is divided into two subsamples, i.e., the primary and secondary parts. The primary ∼264 million sources have either or both Gaia and SDSS astrometry, with a typical precision of 2.0–5.0 mas yr−1. The secondary ∼136 million sources only have PS1 astrometry, where the average precision is worse than 15.0 mas yr−1. All the proper motions have been validated using QSOs and the existing Gaia proper motions.

The Beijing–Arizona Sky Survey (BASS) is a wide and deep imaging survey that covers a 5400 sq. deg area in the northern Galactic cap with the 2.3 m Bok telescope using two filters (g and r bands). The Mosaic z-band Legacy Survey (MzLS) covers the same area in the z band with the 4 m Mayall telescope. These two surveys will be used for spectroscopic targeting by the Dark Energy Spectroscopic Instrument (DESI) in the northernmost portion of the DESI footprint. This paper describes the third data release (DR3) of BASS, which contains the photometric data from all BASS and MzLS observations from 2015 January until the completion of BASS in 2019 March. The median astrometric precision relative to Gaia positions is about 17 mas and the median photometric offset relative to the Pan- STARRS1 photometry is within 5 mmag. The median 5σ AB magnitude depths for point sources are 24.2, 23.6, and 23.0 mag for the g, r, and z bands, respectively. The photometric depth within the survey area is highly homogeneous, and the difference between the 20% and 80% depth is less than 0.3 mag. The DR3 data, including raw data, calibrated single-epoch images, single-epoch photometric catalogs, stacked images, and co-added photometric catalogs.

There are three types of observed data produced by the 13.7-meter millimeter-wave radio telescope. The first type is observed in the single-point observation mode according to the requirements of the observer. Each spectral line contains one Fits file, and one record in the database table corresponds to the header information of one file.A total of 3.06 million spectral lines have been observed since 2003.The second method is to use OTF observation mode to observe data as required by the observer. and two fits cube files are generated after averaging the scan results of the same area mapped every day, with one record in the database corresponding to the header information of that two file. The scan area ranges from 10′ × 10′ to 30′ × 30′, and more than 5,900 areas have been observed since 2011.The third is Milky Way Imaging Scroll Painting (MWISP), It is a large-scale systematic survey for the galactic plane, including 12CO (1-0), 13CO (1-0), and C18O (1-0) molecules.
