tilepix-TILEID.json

Summary:

This file maps the TILEID for an exposure to HEALpix pixels (nested nside=64).

Naming Convention:

tilepix-TILEID.json, where TILEID is the tile id number.

Regex:

tilepix-[0-9]+\.json

File Type:

JSON, 1 KB

Since each exposure observes one tile, the mapping consists of a keyword which is the TILEID to petal number, 0 - 9, which in turn is mapped to the HEALPix pixels that overlap the petal.

Example:

{"51": {"0": [25596, 25598, 25599, 26965],
        "1": [25595, 25598, 25599, 26961, 26964, 26965],
        "2": [26961, 26964, 26965, 26966],
        "3": [26964, 26965, 26966, 26967],
        "4": [26965, 26967, 26973, 27650, 27656],
        "5": [26965, 27648, 27650, 27651],
        "6": [26965, 27648, 27649, 27650, 27651],
        "7": [25599, 26282, 26283, 26965, 27648, 27649],
        "8": [25597, 25599, 26280, 26282, 26965],
        "9": [25596, 25597, 25598, 25599, 26965]}}
