6. Parameters of "Device Table" For XFFTS†

6.1 Procedure of Making Device Table†

1. Enter file name of Device Table
2. Set parameters
3. Save and Set

6.2 Device Table settings†

Fig. 6 shows the appearance of the Device Table. Within this table, you can modify values and toggle the position check marks indicated by the red and blue rectangles. However, the observatory strongly advises against arbitrarily changing the parameters marked in red. Only three parameter sets are recommended, as shown here:
Setting 1 for HCO⁺(4–3) and ¹²CO(3–2) observations
Setting 2 for ¹²CO(3–2) and ¹³CO(3–2) observations
Setting 3 for CI(4–3) and ¹²CO(4–3) observations

Thus, observers must set the parameters marked in red according to one of the settings (1–3), and verify that the values indicated by the yellow rectangle match those of the selected setting.
The check mark in "Tracking" (blue rectangle), indicating the reference frequency for velocity tracking, should be set by the observers based on their observing plan.
