C18O Map of L1251A

The (0,0) position of the L1251A C18O map resulting from this setup is:

R.A.(1950)= 22 30 28.1 Dec(1950)= 74 55 51 (see entry for "Box 1" in the coordinate table) , v_LSR=-4 km/s

Sourcename L1251
Bandwidth 5 MHz
Map Parameters (in Screen 1)

RAST 1=Reference sharing ON

RAST 0=Normal posn sw. mode

RAST 1
Rotation of dewar ROTANG 0
number of footprints from commanded 0,0 XOFF 0
YOFF 1
Size of map in units of short axis of footprint NX 3
Size of map in units of long axis of footprint NY 2
Absolute value should be 5 DX -5

Absolute value should be 6

Sign of DX and DY indicates

direction of footprint offsets in map.

X is always defined relative to the short axis of a footprint, regardless of ROTANG.

DY -6
NMAIN 0
NONS and NBRE should be equal for beam sampling, in decent weather NONS 6
If sky is good: NBRE 6
If sky is bad:

GRID=3=beam sampling

GRID=5=Nyquist sampling

GRID 3
Do CAL every NCALth run. NCAL 6
