Multi-epoch UBVRI photometric catalog of symbiotic stars

TL;DR

This paper provides a comprehensive multi-epoch UBVRI photometric catalog of 83 symbiotic stars, offering precise measurements over several years to aid in the study of these complex stellar systems.

Contribution

It presents the first extensive multi-epoch UBVRI photometric catalog of symbiotic stars, calibrated with existing sequences, covering observations from 1998 to 2002.

Findings

Average of 3.6 epochs per star

Photometric accuracy better than 0.01 mag

Data collected over nearly four years

Abstract

We present a multi-epoch, accurate UBVRcIc photometric catalog of 83 symbiotic stars and related objects, measured while calibrating the Henden and Munari (2000, 2001, 2006) photometric sequences around them. The vast majority of the observations where collected in the time interval between October 19, 1998 to April 21, 2002 with the 1.0-m Ritchey-Chretien telescope of the U. S. Naval Observatory, Flagstaff Station (Arizona). On average, UBVRcIc data are given on 3.6 epochs for each program star. The overall budget error of the data is usually better than 0.01 mag.
