A simple ASCII version of the NDfield format used to represent either uniform grids or particles coordinates. Data type is always interpreted as double precision floating point.
| ANDFIELD COORDS | header (COORDS keyword is optional, if present, values are interpreted as coordinates, or else, as pixel values) |
|---|---|
| [N_1 ... N_ndims] | size of the grid along each of the ndims dimensions (in pixels) or number of dimensions and number of particles if COORDS keyword is in the header (= [ndims,nparticles]) |
| BBOX [X0_1 ... X0_ndims] [delta_1 ... delta_ndims] | OPTIONAL: bounding box definition (origin and extent) |
| V_1 V_2 | values (any number of values can be on the same line) |
| V_3 | no particular formating is required |
| ... | Repeat enough time to define a number of values equal to the number of pixels or the number of particles (if COORDS keyword is in the header) |
