03-AllocateFibers¶
Input data¶
| path name | type | unit | description |
| /gal/ra_true | float array | degrees | galaxy's right ascension (ecliptic or equatorial reference frame? see BCC doc) |
| /gal/dec_true | float array | degrees | galaxy's declination (ecliptic or equatorial reference frame? see BCC doc) |
| /tiling/number_of_tiles | int | none | copied from parameter file for future reference |
| /tiling/tile_centers_{ra,dec} | float array | none | center positions of the tiles (in what reference frame?) |
| /gal/tile_id | int array | none | in which tile does each galaxy lie? -1 if it lies in no tile |
| /gal/survey_selection_flag | bool array | none | does the galaxy lie in a tile? |
Parameters¶
(in param.ini)
| name | type | unit | description |
| fiber_pitch | float | ? | ? |
| fiber_size | float | ? | ? |
| num_fibers_on_diameter | int | none | ratio tile diameter to fiber size |
| n_pass_per_tile | int | none | how often will each tile be passed |
| patrol_radius | float | deg | ? |
| allocation_method | string | none | ? |
Output¶
| path name | type | unit | description |
| /gal/tile_id | int array | none | to which tile has each galaxy been assigned (-1 if none) |
| /gal/visit_id | int array | none | on which pass of the tile has the galaxy been assigned to a fiber (value if none: ?) |
| /gal/fiber_id | int array | none | to which fiber has the galaxy been assigned (value if none: ?) |
| /gal/fiber_selection_flag | bool array | none | could the galaxy be covered by a fiber? |
