Hi Bill,

Is there a way to draw a map with an RA/Dec Grid for an old epoch in a simple cylindrical projection.
If I keep the J2000 frame for the grid, the lines are straight horizontal or vertical, but with the frame for the date (say BC1500) the lines are badly curved.

NB: In the .mar file and in ticks, grids etc . , I replaced all the J2000.0 by D0.0, to get all the lines for the date.

Thank you,
Luc Desamore
