Detection and Classification of Astronomical Targets with Deep Neural Networks in Wide Field Small Aperture Telescopes
Peng Jia
This is code for the paper "Detection and Classification of Astronomical Targets with Deep Neural Networks in Wide Field Small Aperture Telescopes". It is a deep learning framework used for celestial objects detection and classification. The code is written by Pytorch and can be used to process any images obtained by wide field sky survey telescopes.

LAMOST-II MRS SPCANet catalog
Rui Wang / A-Li Luo
The catalog of stellar parameters and chemical abundances contains information of 1,472,211 LAMOST-II MRS spectra. The information in the catalog contains: the identifier for the corresponding star, Gaia identifier, LAMOST spectrum identifier, coordinate information, signal-to-noise of the spectra (S/N), radial velocities without calibration, effective temperature, surface gravity and elemental abundance ([X/H]) derived by SPCANet.

THE SEPARATION DISTRIBUTION OF ULTRA-WIDE BINARIES ACROSS GALACTIC POPULATIONS
Haijun Tian / Kareem El-Badry / Hans-Walter Rix / Andrew Gould
We have compiled an extensive catalog of candidate wide binaries selected from Gaia DR2 in the solar neighborhood with distances $d<4$~kpc, following a procedure similar to that of El-Badry & Rix(2018). This initial candidate catalog consists of 807,611 possible binaries. Its contamination rates are lower than 10% at $a<20,000$~AU; however, the contamination rates quickly increase beyond 20,000~AU, until up to 100% at the largest separation bin, i.e., a = 1.0 pc. To address this, we subsequently applied additional selection criteria, tailored towards three kinematically-selected, presumably pure subsamples: 4361 disk-like, 10090 intermediate, and 4351 halo-like binaries.

LAMOST Medium Resolution Survey Radial Velocity Catalog
This catalog provides radial velocity (RV) measurement for 1,594,956 spectra (each spectrum has two wavebands) of the LAMOST-II medium resolution (R~7500) survey. Employing a set of RV standard stars, the zero-point of the measurement have been calibrated. Some reference RV datasets derived from medium/high-resolution observations have been used to evaluate the accuracy of the measurement. Comparing with reference sets, the accuracy of our measurement can get 0.0227 km/s to radial velocities standard stars. The intrinsic precision is estimated with the multiple observations of single stars, which can achieve to 1.36km/s, 1.08 km/s, 0.91 km/s for the spectra at signal-to-noise levels of 10, 20, 50, respectively.

Solar Image Restoration with the Cycle-GAN Based on Multi-Fractal Properties of Texture Features
Peng Jia / Yi Huang / Bojun Cai / Dongmei Cai
This is the original code for paper 'Solar Image Restoration with the Cycle-GAN Based on Multi-Fractal Properties of Texture Features', which will be published in APJ Letters. It uses several high resolution images as reference to restore any frame of blurred solar images.
