GbmSaaPolygon11

class gdt.missions.fermi.gbm.saa.GbmSaaPolygon11

Bases: GbmSaaPolygon5

The coordinates of the GBM SAA boundary in latitude and East longitude used from 18:27:00 UTC on November 17, 2023 until 19:15:00 UTC on July 23, 2024.

Note: Reversion to the same shape as GbmSaaPolygon5 following the test of GbmSaaPolygon10.

Attributes Summary

latitude	The latitude points of the boundary
longitude	The longitude points of the boundary

Methods Summary

is_closed()	Test if the boundary represents a closed polygon.
is_convex()	Test if the boundary represents a convex polygon.

Attributes Documentation

latitude

The latitude points of the boundary

Type:

(np.array)

longitude

The longitude points of the boundary

Type:

(np.array)

num_points

Number of vertices in polygon

Type:

(int)

Methods Documentation

is_closed()

Test if the boundary represents a closed polygon. A closed polygon is one where the first and last points are equal.

Returns:

(bool)

is_convex()

Test if the boundary represents a convex polygon. The test is performed by measuring every interior angle of the polygon and checking if all angles are < 180 deg. The definition of a convex polygon is one where all interior angles are < 180 deg.

Returns:

(bool)
