This site hosts a list of candidate dwarf galaxies returned by a comprehensive search in the Gaia DR2 data using an algorihtm based on the wavelet transform. For a more in-depth description see the full text. The current list has been cross matched with EDR3, but does not contain the full EDR3 analysis.
|SIGNIFICANCE||wavelet significance (Darragh-Ford et al. 2020)|
|DES_FOOTPRINT||TRUE if in DES Footprint|
|PS1_FOOTPRINT||TRUE if in PS1 Footprint|
|DELVE_FOOTPRINT||TRUE if in DELVE Footprint|
|DECALS_FOOTPRINT||TRUE if in DECals Footprint|
|EBV_FLAG||TRUE if E(B-V) > 0.2|
|PMRA||Average proper motion value (mas/yr)|
|PMDEC||Average proper motion value (mas/yr)|
|EDR3||Significance of cross-matched EDR3 hotspot (0 if no EDR3 hotspot)|
|RR_LYRAE||TRUE if candidate contains rr lyrae|
|NSTARS||Number of stars in candidate|
|MAG_AVG||Average magnitude of stars in candidate|
|MAG_MAX||Magnitude of brightest star in candidate|
Gold Standard with RR Lyrae Candidate List
This candidate is not associated with any known dwarfs or globular clusters. However, it is near the Orion molecular complex making dust contamination a potential issue for both Gaia completeness in the region and the interpretation of stellar colors and magnitudes due to extinction uncertainties (Rezaei et al. 2018).
This candidate is likely associated with the Virgo Stellar Stream. The distance of the stream (19 kpc) broadly agrees with the color–magnitude distribution of candidate stars and the associated RR Lyrae has been previously associated with the stream (Prior et al. 2009).
