toasty cascade
¶
The cascade
operation computes lower-resolution tiles from higher-resolution
tiles. The same algorithms apply to either studies or all-sky TOAST pyramids.
Usage¶
toasty cascade {--start DEPTH} PYRAMID-DIR
The PYRAMID-DIR
argument gives the location of a directory containing tile
pyramid data files. The --start DEPTH
argument gives the depth at which
tiles already exist. For instance, with --start 5
, the pyramid should
contain level-5 tiles, and the cascade will fill in tiles between levels 4 and
0, inclusive.
