fill.grid: Fill a box with overlapping tiles

In AngusWright/LAMBDAR: Measure galaxy fluxes from an arbitrary FITS image using input aperture locations and dimensions

Fill a box with overlapping tiles

Description

Tile a box of radius 'rad' within the limits of 'ra' and 'dec', with overlaps of size 'buffer'.

Usage

fill.grid(ra, dec, buffer=0.1, rad=sqrt(3)/2, buffer.edge=TRUE, plot=TRUE, main="Block Coverage Map")

Arguments

ra	numeric vector; The RA limits of the box, in degrees.
dec	numeric vector; The DEC limits of the box, in degrees.
buffer	numeric; The overlap between adjacent tiles, in degrees.
rad	numeric; The radius of each tile, in degrees.
buffer.edge	logical; do we need to buffer the limits of the box as well?
plot	logical; do you want a plot of the box and tiles?
main	string; the title for the plot.

Value

array of dimension 2; the central RA and DEC positions of each tile.
