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
