|11||MLET_DEC||MUSELET Decl. (J2000) in units of decimal degreesd|
|12||EML_ONLY||Flag (boolean) for the objects detected only by ORIGIN or MUSELET (i.e., no UVUDF counterpart)|
|13||REF_SPEC||The main spectrum (PSF-weighted or MUSE white-light weighted) used to measure redshift|

|18||F775W_MAG||HST F775W magnitude (AB) from Rafelski et al. (2015)e or NoiseChiself|
|19||F775W_MAG_ERR||The errors on the HST F775W magnitude (AB)ef|
|20-41||[LINE]_FLUX||Line fluxes (10-20 erg s-1 cm-2) summed over the entire mask apertureg (see Sect. 3.3)|
|[LINE]_FLUX_ERR||Errors on the line fluxes|
|Columns that only exist in the combined catalog|
|45||Z_FROM||The origin of the redshift (the udf-10 or the mosaic catalog)|
|46||IN_UDF10||Flag (boolean) indicating an object in the udf-10 field|
Notes. The full table is available at the CDS.
For the future release, if an object can be “split” into multiple objects in terms of their redshift identifications, then the original MUSE_ID will be deleted and the new IDs of the split objects will be added to the catalog.
When MERGED = True, the coordinates are calculated as HST F775W flux weighted coordinates of all objects composing the new merged source (see Sect. 3.1.1). Otherwise, they are identical to the UVUDF catalog (Rafelski et al. 2015).
When ORIG_ID or MLET_ID is empty, this indicates that the object is not detected by ORIGIN or MUSELET. For the combined catalog, the column names of ORIG_ID, ORIG_RA, and ORIG_DEC have a suffix of _UDF10 and _MOSAIC.
