AstroGridLinesStyle

is an option for AstroGraphics that specifies how coordinate grid lines should be rendered.

Details

AstroGridLinesStylestyle specifies that all astro grid lines should be rendered by default with the specified style.
AstroGridLinesStyle{style₁,style₂} specifies separate styles for the lines of constant first coordinate (generally a longitude angle like right ascension or azimuth) and the lines of constant second coordinate (generally a latitude angle like declination or altitude).
Styles can be specified using graphics directives such as Thick, Red and Dashed, as well as Thickness, RGBColor, Dashing and combinations given by Directive.
Explicit styles specified in the settings for AstroGridLines can override styles specified in AstroGridLinesStyle.
AbsoluteOptions can be used to extract explicit styles that were used for AstroGridLines with Automatic settings.
