ObjId = 588017566026498209


or just coincidental alignment....

ed: I measured the angles, and they're all approximately the same, 2.4 x 10-3 deg, taken using the ra dec on the navigate tool. A bit crude, but even using a ruler on the screen, they are almost equidistant.

Nope, that's just a coincidental alignment (it looks to be, at least).
The only thing that interferes with my learning is my education.

Pretty strange grouping, I must agree  ;)
(1) measured z, (4) PhotoZ,  best guest is that all could be the same neighborhood,
but most likely not. Results are not conclusive.

objID   588298664122777945
Redshift: 0.335792 +/- 0.000153
z              0.333822 +/- 0.018       Photometric Z seems pretty close
photozcc2  0.329139 +/- 0.022
photozd1    0.343968 +/- 0.019
