Sommario:
- <p>This dataset contains <strong>visual magnitude estimates of the variable star GN Sge</strong>, obtained from photographic observations made with the <strong>Seven-Camera Astrograph of the Odessa Astronomical Observatory</strong>. The magnitudes were estimated visually from photographic plates.</p> <p>The data are provided as a time series of <strong>Julian Dates (JD)</strong> and corresponding stellar magnitudes in the <strong>photovisual magnitude system</strong>. All Julian Dates are strictly increasing and unique. The numerical precision of the original measurements is fully preserved.</p> <p>A colon “:” following a magnitude denotes an <strong>uncertain visual estimate</strong>, in accordance with standard variable-star observing practice. Unmarked values represent normal-confidence estimates.</p> <p>The dataset is intended for studies of long-term variability, historical light-curve reconstruction, and comparison with catalog and survey data. It supplements information available in major astronomical databases such as SIMBAD and the General Catalogue of Variable Stars (GCVS).</p> <p><strong>Data summary:</strong><br>– Number of observations: <strong>534</strong><br>– Julian Date range: <strong>JD 2436381.4712 – 2443069.2674</strong><br>– Observation type: visual estimates from photographic plates<br>– Instrument: Seven-Camera Astrograph, Odessa Astronomical Observatory<br>– Magnitude system: photovisual</p>
