Radio identification of decameter-wave sources. II: The 30deg<delta<40deg declination interval

TL;DR

This study identifies and characterizes decameter-wave radio sources within a specific declination range, cross-matching with existing catalogs and analyzing their spectra to enhance source classification.

Contribution

It provides a detailed identification and spectral analysis of 876 decameter-wave sources in the 30°<delta<40° declination interval, expanding the cataloged data and spectral understanding.

Findings

221 sources have straight-line spectra with alpha<-1.0

Spectra of all 876 sources were derived and fitted

Sources are cataloged in the CATS database

Abstract

This paper is dedicated to the identification of decameter-wave sources of the UTR catalog within declination interval 30deg<delta<40deg. UTR sources are cross-identified with CATS database catalogs within 40'x40' error boxes. The sources are deblended using the data on the coordinates of the objects and the behavior of their continuum radio spectra. The spectra of 876 sources are derived and fitted by standard analytical functions. Of these sources, 221 objects have straight-line spectra with spectral indices alpha<-1.0. All objects are catalogued and stored in the CATS database.
