Recommended parameters

For DASH345

time for a scantscan [s]60
number of ON-scan per OFFNscan(SEQ)2
separation between scans(delta)l [arcsec]8
map gridd [arcsec]8
system noise temperatureTsys [K]300
※MAKE SURE that the recommended scan speed is less than 55"/sec.
For 'resolution bandwidth', 608 kHz ≒ 0.5 km/s

For CAT8W

time for a scantscan [s]30
number of ON-scan per OFFNscan(SEQ)1
separation between scans(delta)l [arcsec]6
map gridd [arcsec]6
system noise temperatureTsys [K]600
※MAKE SURE that the recommended scan speed is less than 40"/sec.
For 'resolution bandwidth', 760 kHz ≒ 0.5 km/s
