Questions

What does the poster actually show?

A smooth curve tracing the hours of daylight for every day of the year in São Luiz Gonzaga — from the shortest day in winter to the longest in summer and back again. The X axis is the calendar; the Y axis is daylight duration. The chart is framed with the city name, coordinates, and year. An optional occasion marker pins a specific date on the curve.

How accurate is the astronomy for São Luiz Gonzaga?

Very. Daylight hours are computed using Spencer's (1971) solar declination formula with a −0.833° correction for atmospheric refraction and the sun's semi-diameter — matching the standard used by professional almanacs. The coordinates used are -28.40833, -54.96083.

What size is the print and what paper?

50×70 cm (approx. 20×28 in) on 170 gsm uncoated matte paper. It prints at 300 dpi from a 5906×8268 px source file. The finish is soft and anti-reflective. Frame not included.
