Step 1: Open the Terminal by clicking the desktop icon in AWS.†
Step 2: In the Terminal, start the "otfaste.pl" program, then input the desired parameters.†
Step 3: Check the 'Total time per one map' and 'Optimal OFF-point integration time'†
Recommended parameters†
For DASH345†
time for a scan | tscan [s] | 60 |
number of ON-scan per OFF | Nscan(SEQ) | 2 |
separation between scans | (delta)l [arcsec] | 8 |
map grid | d [arcsec] | 8 |
system noise temperature | Tsys [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 scan | tscan [s] | 30 |
number of ON-scan per OFF | Nscan(SEQ) | 1 |
separation between scans | (delta)l [arcsec] | 6 |
map grid | d [arcsec] | 6 |
system noise temperature | Tsys [K] | 600 |
※MAKE SURE that the recommended scan speed is less than 40"/sec.
For 'resolution bandwidth', 760 kHz ≒ 0.5 km/s
