AstroGridLines

AstroGridLines

is an option for AstroGraphics that specifies the coordinate grid lines to show on the celestial sphere.

Details

  • Different astro reference frames have different coordinate grid lines.
  • For equatorial frames, the astro grid lines are lines of constant declination (parallels) and lines of constant right ascension (meridians).
  • For horizon frames, the astro grid lines are lines of constant altitude (almucantars) and lines of constant azimuth.
  • The following settings can be given for AstroGridLines:
  • Noneno astro grid lines drawn
    Automaticastro grid lines placed automatically
    napproximate number of coordinate lines
    Quantity[…]astro grid lines placed at multiples of an angular quantity
    {grid1,grid2}astro grid lines specified separately for each angular direction
    {frame1spec1, frame2spec2,…}draw several sets of astro grid lines for respective frames
  • With the Automatic setting, astro grid lines are usually placed at points whose coordinates have the minimum number of digits in their decimal representation.
  • For each angular coordinate, the following grid line options can be given:
  • Noneno geo grid lines drawn
    Automaticgeo grid line positions chosen automatically
    napproximate number of coordinate lines
    Quantity[…]astro grid lines placed at multiples of an angular quantity
    {x1,x2,…}astro grid lines drawn at the specified positions
    {{x1,style1},…}astro grid lines with specified styles
    funcfunction to be applied to xmin, xmax to get astro grid line option

AstroGridLines Styling  (2)

Astro grid lines are styled by default with the same color of the corresponding plane:

Specify the style of each astro grid line:

Specify the style of all astro grid lines using AstroGridLinesStyle:
