02-TileSurvey¶
Input data¶
| path name |
type |
unit |
description |
| /gal/target_selection_flag |
bool away |
none |
has the galaxy been selected as a target? |
| /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) |
Parameters¶
(in param_target_selection.ini and config/pipeline.yaml)
| name |
type |
description |
| number_tiles |
int |
how many tiles should be scheduled |
| fields |
dict of lists |
which fields (sky rectangles) should be observed |
Output¶
| path name |
type |
unit |
description |
| /gal/survey_selection_flag |
bool array |
none |
does the galaxy lie in a tile? |
| /tiling/{ra,dec}_{min,max}_tot |
float |
delimitation of the smallest sky rectangle containing all fields |
| /tiling/number_of_tiles |
int |
copied from parameter file for future reference |
| /tiling/tile_centers_{ra,dec} |
float array |
center positions of the tiles (in what reference frame?) |
| /tiling/tile_observation_time |
? |
when will the tile be observed? (format?) |
| /tiling/airmass |
float array |
the airmass in each tile |
| /gal/tile_ID |
int array |
in which tile does each galaxy lie? -1 if it lies in no tile |
| /gal/survey_selection_flag |
bool array |
True if the galaxy lies in a tile, i. e. tile_ID is not -1 |
