***Tips for otf observations: [#if70a099]
+Set the '''Calibration Integration Time''' equal to the OFF position Integration time~
+Set the '''Interval''' to be 15-20min by estimating the time for 1 scan. (e.g., if '''Total time per one map''' = 60min and the number of scans = 60, the time for 1 scan = 1min. Thus, 15-20min corresponds to 15-20 scans. So input 15-20 as '''Interval''')~
+''&color(red){You can find appropriate '''OFF position Integration time''' and '''Total time per one map''' from };'' [[HERE>_Tools/otfaste.pl]].~

***Recommendations for otf observations: [#xd44ecf4]
+Observation parameters—especially integration time—depend on airmass and weather conditions. Therefore, observers should adjust these parameters to match the current conditions.
+For observations with Tsys > 600 K, which frequently occur at 400 GHz or higher, we recommend setting the '''On Position Integration Time''' (i.e., time per scan) to less than 30 seconds, and '''the number of ON scans per OFF''' to 1 (i.e., Sequence Pattern 1*).
+Tsys is ''highly'' depends on the source's elevation at 400 GHz or higher. This should be also keep in mind.
