Methanol and water maser observations separate disc and outflow sources
  in IRAS 19410+2336
  We investigate the kinematics of high mass protostellar objects within the
high mass star forming region IRAS 19410+2336. We performed high angular
resolution observations of 6.7-GHz methanol and 22 GHz water masers using the
MERLIN (Multi-Element Radio Linked Interferometer Network) and e-MERLIN
interferometers. The 6.7-GHz methanol maser emission line was detected within
the $\sim$ 16--27 km s$^{-1}$ velocity range with a peak flux density $\sim$50
Jy. The maser spots are spread over $\sim$1.3 arcsec on the sky, corresponding
to $\sim$2800 au at a distance of 2.16 kpc. These are the first astrometric
measurements at 6.7 GHz in IRAS 19410+2336. The 22-GHz water maser line was
imaged in 2005 and 2019 (the latter with good astrometry). Its velocities range
from 13 to $\sim$29 km s$^{-1}$. The peak flux density was found to be 18.7 Jy
and 13.487 Jy in 2005, and 2019, respectively. The distribution of the water
maser components is up to 165 mas, $\sim$350 au at 2.16 kpc. We find that the
Eastern methanol masers most probably trace outflows from the region of
millimetre source mm1. The water masers to the West lie in a disc (flared or
interacting with outflow/infall) around another more evolved millimetre source
(13-s). The maser distribution suggests that the disc lies at an angle of
60$^{\circ}$ or more to the plane of the sky and the observed line of sight
velocities then suggest an enclosed mass between 44 M$_{\odot}$ and as little
as 11 M$_{\odot}$ if the disc is edge-on. The Western methanol masers may be
infalling.
