Methods Documentation

__call__(tel_id: int, time: Time) → tuple[Quantity, Quantity]

Interpolate alt/az for given time and tel_id.

Parameters:

tel_idint

Telescope id.

timeastropy.time.Time

Time for which to interpolate the pointing.

Returns:

altitudeastropy.units.Quantity[deg]

Interpolated altitude angle.

azimuthastropy.units.Quantity[deg]

Interpolated azimuth angle.

add_table(tel_id: int, input_table: Table) → None

Add a table to this interpolator.

Parameters:

tel_idint

Telescope id.

input_tableastropy.table.Table

Table of pointing values, expected columns are time as Time column, azimuth and altitude as quantity columns for pointing and pointing correction data.
