GbmSaaPolygon2

class gdt.missions.fermi.gbm.saa.GbmSaaPolygon2

Bases: SouthAtlanticAnomaly

The coordinates of the GBM SAA boundary in latitude and East longitude used from 18:30:09 UTC on June 9, 2010 until 17:41:58 UTC on June 10, 2010.

Note: This smaller region was proposed by Jerry Fishman to increase observing time. It resulted in too many local particle triggers so it was adjusted via GbmSaaPolygon3 and GbmSaaPolygon4.

Attributes Summary

latitude	The latitude points of the boundary
longitude	The longitude points of the boundary
num_points	Number of vertices in polygon

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)
