Galaxy Class Comments
NGC0448 I+s The ETG is in a tidal interaction with a disturbed companion.
NGC0474 M+s+r+ph The ETG is surrounded by multiple concentric shells and hosts several radial streams. Its outer halo reaches the disk of the unperturbed companion spiral galaxy, NGC 0470.
NGC0502 M+t?+r?+ah-wc-h The stellar halo of the ETG is asymmetric, possibly due to the presence of a diffuse tidal tail and/or a shell.
NGC0509 R-pc
NGC0516 R-pc
NGC0524 U-pc-h The ETG is surrounded by galactic cirrus and extended halos from bright stars, preventing the detection of fine structures around it.
NGC0525 R-pc-h
NGC0661 U+ah-pc The ETG is surrounded by galactic cirrus and extended halos from bright stars, preventing the detection of fine structures around it.
NGC0680 I+t+s+r+ph+wl-wc The ETG is tidally disturbed, showing two extended tidal tails, and an asymmetric stellar halo. It has a bright edge-on companion in its vicinity. Whether the tidal tails result from this on-going interaction or a past major merger is unclear.
NGC0770 I+t-pc The ETG lies within a prominent tidal tail. It is likely a satellite of the massive perturbed spiral NGC 0772, and is currently tidally disrupted.
NGC0936 C+s+wl A stellar stream hosting a tidally disrupted companion wraps around the ETG.
NGC1023 U+ah-h The stellar halo of the ETG seems to be slightly disturbed, but the extended halos of two bright nearby stars hamper the classification.
NGC1121 U-h The ETG totally lies within the reflection halo of a bright star, preventing the detection of fine structures.
NGC1222 M+t+r?+ph+pl The ETG exhibits multiple signs of a relatively recent gas-rich merger: tidal tails, perturbed main body, dust lanes.
NGC1248 R-pc-h The ETG does not show any evident sign of disturbances although it makes a close pair with the undisturbed spiral galaxy Mrk 604.
NGC1266 C+s?+wl-pc The ETG has several low mass companions, with possibly a tidally disrupted one. Note however the high level of cirrus contamination.
NGC1289 U+s?+wl-pc Model subtraction of the ETG reveals a slightly perturbed central body with possibly a faint stream. However Galactic cirrus prevents a firm classification.
NGC1665 U-h The ETG is surrounded by a ring like structure probably made of old stars. Prominent Galactic cirrus is present in the field.
PGC016060 C+d+pl The galaxy is surrounded by a warped star-forming ring, and is possibly interacting with an early-type companion to the East.

NGC2481 I+t?-wc The ETG and its disturbed companion NGC 2480 make an interacting pair. The prominent tidal tails shown by the system likely come from the companion galaxy.
NGC2577 C+s-wc The ETG has a regular main body with one radial stellar stream sticking out to the North, hosting a possible progenitor.
NGC2592 C+s+r-pc The ETG is surrounded by cirrus. However the filament to the East is most likely a stellar stream as it hosts a putative progenitor.

NGC2778 R The ETG does not show any evidence of a tidal perturbation though it makes a close pair with the massive companion NGC 2779.
PGC028887 U-h The ETG is apparently relaxed, though its stellar halo hosts two possible companions, one with a stream (but the physical association is unsure). The presence of an extended reflection halo is problematic for the galaxy classification.

NGC3384 I+ah The main stellar body of the ETG is asymmetric. It makes a pair with the ETG NGC 3379 and is believed to have been involved in a fast encounter with M96 that possibly formed the huge HI ring surrounding the system (known as the Leo Ring).
NGC3400 R
NGC3414 I+s+ph The disturbed ETG is in interaction with the tidally disturbed companion NGC 3418. It is crossed by a very extended South-North stellar stream. Its progenitor is visible to the South. To the North, the stream ends in a shell-like structure.
NGC3457 R+wl-wc

NGC3599 R
NGC3605 U-h The ETG is observed towards the halo of its companion NGC 3607. This prevents the detection of fine structures.
