Abstract:
We present high spatial resolution spectroscopic observations of the
proplyd 167-317 (LV2) near the Trapezium cluster in the Orion Nebula,
obtained during the system verification run of the Gemini Multi-Object
Spectrograph (GMOS) Integral Field Unit (IFU) at the Gemini South
Observatory. We have detected 38 forbidden and permitted emission
lines associated with the proplyd and its redshifted jet.
Description:
The data were taken during the system verification run of the GMOS IFU
(Gemini Multi-Object Spectrograph Integral Field Unit) at the GST
(Gemini South Observatory), under the GS-2003B-SV-212 program, on 2004
February 26 and 27.

Note (1): The spectral regions R1, R2, R3 and R4 are defined in Figure 1.
In units of 10-15erg/s/cm2/pix.
Note (2): Flags on the mean fluxes and line ratios, defined as follows:
b = Implies that Iregion-Ibackground<0.
N = Implies that the line was not detected in that region.
e = Absolute error smaller than 6.10-4.
Note (3): The spectral regions R1, R2, R3 and R4 are defined in Figure 1.
Relative to Hα, where Hα=100.
