Table C.1
Description of the columns.
| Column Nr & Name | Description |
|---|---|
| (1) Name | Object Names from literature (reference source given in Reference column). Priority was given to information from Milliquas due to completeness. Names for CDFS objects were derived from their position in the HHMMSS.SS+DDMMSS.S. format. Names provided by eJWST should be taken with caution, because these are usually introduced by the proposer and typically do not follow a standard convention. |
| (2–3) RA/Dec (J2000, deg) | Target coordinates (J2000, in degrees) from literature. Rounded to 7 decimals for display purposes and to avoid truncation. To see real accuracy, go to corresponding catalogue coordinate column (RA (catalogue)/Dec (catalogue)). Coordinates taken from Gaia were shifted to J2000. See Sect. 3.4 for more information. |
| (4) objType | Classification of the source (e.g. Seyfert, QSO, BL Lac, LINER, etc.), retrieved from proposer descriptions for targeted AGNs and from catalogues for non-targeted AGNs. Cataloguespecific codes were harmonized into a unified scheme; ‘NL’ and ‘BL’ indicate narrow-line or broad-line objects, ‘?’ marks uncertain types, and ‘??’ highly questionable classifications. Proposer Descriptions are kept as provided by the eJWST archive. |
| (5) Ref | Original publication used to determine first four columns. When an object was listed in multiple catalogues, the following priority was used (from left to right): Milliquas – MaNGA eFEDS – Stripe – CDFS – BASS – Veroncat – Rosat – eJWST – Gaia – Swiftbat. This order was determined by how complete, updated and accurate the information from the individual catalogues were. All catalogues that do not provide reliable (or any) redshifts for the sources were placed close to the bottom. |
| (6) z | Redshift from literature. Retrieved either from NED or directly from the catalogues used. NED values were given priority. See Sect. 3.5 for more information. Missing redshifts were marked as NaN. |
| (7) zType | Technique by which the redshift was determined. Information were taken from NED (using its standard convention) or, if unavailable, from the catalogues. NED values were given priority. Catalogue-specific terms were harmonized to a common scheme (spectroscopic = ‘ S ‘, photometric = ‘ P ‘) to be consistent with the NED convention; unknown cases are marked with ‘U’. |
| (8) zRef | Redshift reference in the form of a bibcode for each object. Values were taken from NED when available, otherwise from the respective catalogues. |
| (9) zNED | Flag indicating whether redshift information was taken from NED (‘y’) or not (‘n’). |
| (10) Observation ID | Unique identifier for an observation. |
| (11) Instrument | Name of the instrument used for this observation. |
| (12) Aperture | Unique targetable fiducial point and its associated region per Instrument |
| (13) Exptype | Exposure type – type of data in the exposure. |
| (14) Filter | Bandpass filters in different wavelengths. |
| (15) Calibrationlevel | Calibration level with Planned observations =−1 and Science-ready observations =3 |
| (16) Exptime (s) | Total exposure time. |
| (17) Public | States if the observation is public or not (True or False). Public = for all available, otherwise restricted to proposer for a certain period of time. |
| (18) Proposal ID | Collection-specific unique proposal identifier. |
| (19) Release Date (UTC) | Date the metadata for an observation is public (UTC). |
| (20) Intent | |
| Intended purpose of observation (Science, Calibration, Background). | |
| Labelled as follows: | |
| Science = Scientific observations done with the purpose of targeting a specific object or area in the sky. | |
| Calibration = Observations used to calibrate the science instruments and observing modes. | |
| Background = Background observation listed by MAST portal or found through eJWST keywords. | |
| (21) Central Wavelength (μ m) | Central wavelength of the observation. |
| (22) Targeted | Checks if object was targeted by JWST or not (True or False; see Sect. 3). |
| (23) Data Link | Link for direct data product download when observations are public. |
| (24) Proposal ID Link | Link to programme information for specific proposal ID. |
| (25) TSOVISIT | Flag indicating whether an observation is a TSO or not (‘t’ or ‘f’). Nan values were assigned for observations not including this keyword on the eJWST archive. |
| (26) eJWST Name | Name of object as given by the proposer, listed as target_name in eJWST. |
| (27) RA (eJWST) | Right ascension in deg and J2000, listed as targetposition_coordinate_cval1 in eJWST. |
| (28) Dec (eJWST) | Declination in deg and J2000, listed as targetposition_coordinate_cval2 in eJWST. Note: These coordinates are found in jwst.observation, in jwst.archive the same keywords store the pointing coordinates of the instruments per observation. |
| (29) objType (eJWST) | Classification of object as listed by proposer in the eJWST archive. |
| (30) z (NED) | Redshift taken from the astronomical database NED by a coordinate search with 1 arcsec radius. |
| (31) zType (NED) | Technique used to determine the redshift. Information taken from the astronomical database NED by a coordinate search with 1 arcsec radius. |
| (32) zRef (NED) | Redshift Reference taken from the astronomical database NED by a coordinate search with 1 arcsec radius. |
| Name (*) | Name of object taken from (*) catalogue. |
| ID (*) | Source ID in (*) catalogue, when available. |
| RA (*) | Right Ascension in decimal degrees (J2000) taken from (*) catalogue. |
| Dec (*) | Declination in decimal degrees (J2000) taken from (*) catalogue. |
| z(*) | Redshift taken from (*) catalogue, when available. |
| zType (*) | Technique used to determine the redshift. Information taken from (*) catalogue, when available. Spectroscopic redshift was labelled ’spec’, photometric ‘phot’ and unknown cases ‘?’. |
| zRef (*) | Redshift Reference of object taken from (*) catalogue, when available. |
| objType (*) | Classification of object taken from (*) catalogue, when available. |
