SWAG aims to map the inner ~3x0.7 degrees of our Milky Way and to capture most of the molecular emission in the Central Molecular Zone. This will be achieved by ~6500 individual pointings with the Australia Telescope Compact Array with integration times of ~4min per pointing.
The frequency ranges are: 21,200 - 23,200 MHz & 23,600 - 25,600 MHz
and we set up high spectral resolution "zoom" modes to cover the following 42 spectral lines:
NH3 (1,1), (2,2), (3,3), (4,4), (5,5), (6,6), (2,1), (3,2), (4,3),
H64a, H66a, H80b,
He66a He67a,
C64a, C66a,
H2O (6(16)-5(23))
CH3OH(3(21)-2(13)), (3(21)-3(12))
HCN(10-10;v=2)
OH (J=9/2;F=5-5),
HNCO(1(01)-0(00)),
NH2CHO(1(01) − 0(00)),
c-C3H2(2(20)-2(11)),
HOCO+(1(01)-0(00)),
CCS(1(2)-0(1)), (N=6-5, J=5-5),
OCS(2-1),
HC5N(8-7),
trans-ethanol (2(21)-3(12)),
