Abstract:
Measurements of the 616 -> 523 line of H2O at 1.3cm in the Orion
region of star formation are reported. With a spatial resolution of
∼0.1", H2O maser emission was detected in two regions: Orion BN/KL
and Orion S. The well-known masers in the BN/KL region are distributed
in a 30"x30" area. The "shell" masers, within the BN/KL region, are
distributed in a 2" by 0.5" strip centered on radio source I and are
offset from IRc2.
Description:
The radio wavelength observations were made in 1991 August 5 under
good weather conditions with the VLA 4 A configuration, which
nominally provides baseline lengths from 0.68 to 36.4km. The total
duration of the observations was 5h.
