The unit of `"_r"` suddenly disappeared from the Vizier result table.
Hi, I recently found that the Vizier query no longer gives the unit of angular separation _r in the result table, which makes error with previous codes I wrote.
I'm just wondering if this is just a temporary thing or intentional update.
This is one of my result table which I got few days ago,
_r RAJ2000 DEJ2000 ... yKmag e_yKmag yFlags
deg deg deg ... mag mag
-------- ------------- ------------- ... ------- ------- --------
0.013524 204.373110760 -9.504518530 ... 15.3153 0.0080 115000
0.016672 204.377877590 -9.502094490 ... 19.7155 0.0360 115000
...
and this is a result table now. The unit of _r is missing.
_r RAJ2000 DEJ2000 _2MASS Jmag ... Bflg Cflg Xflg Aflg
deg deg mag ...
float64 float64 float64 str17 float32 ... str3 str3 uint8 uint8
------- ---------- ---------- ---------------- ------- ... ---- ---- ----- -----

10.135 299.587491 35.203217 19582099+3512115 10.285 ... 111 c00 0 0

Thank you!
I'm not aware of any changes that would have caused this; it could have been an upstream change (i.e., a change in what Vizier returns).
Could you post the queries (or minimal versions of the queries) that produced those results?
The minimal examples will be like
from astroquery import vizier
v = vizier.core.Vizier(columns=["*", "+_r"], catalog="II/246")
result = v.query_region("HD 226868", radius="20s")
table = result['II/246/out']
or, with another catalog,
v = vizier.Vizier(columns=["*", "+_r"], catalog="II/349/ps1")
q = v.query_region('3C 273', radius=rad)
tables = q[0]
table["_r"].unit
The issue is upstream. Thanks for reporting!
@gilleslandais : I can reproduce directly with the votable output on the webpages. None of the calculated columns have a unit. However, they are correctly included in the html output.
