### TIP

`TIP` (antenna tipping or ``skydip'') observations are done to measure the transmission of the Earth's athmosphere, by taking data at several points with the same azimuth but different elevations, spaced by equal steps in ``air mass''.

It is ESSENTIAL that the switching mode is TOTAL POWER during `TIP`.

This is in particular an important step in the calibration of observations with the bolometer.

The basic parameters of this observing mode and its options are: the azimuth, the range and step in airmass, and the time per subscan.
