QC1 parameters written in QC1 database: QC1 DB names: num_stars | num_fields | zeropoint | sigma_zeropoint | ext_coeff_used | sig_ext_coeff |
col_term_used | sig_col_term | colour
All parameters are calculated by the pipeline recipe.
Description of algorithms: num_stars: number of stars used in zeropoint computation num_fields: number of fields used in zeropoint computation zeropoint: averaged zeropoint of the night (in ADU) sigma_zeropoint: error of night zeropoint ext_coeff_used: fixed value sig_ext_coeff: n/a col_term_used: fixed value sig_col_term: n/a colour: colour used
