lsst.sims.ocs.configuration.field module

class lsst.sims.ocs.configuration.field.Field(fid, fov, ra, dec, gl, gb, el, eb)

Bases: future.types.newobject.newobject

Class for handling field information.

This is the class for handling the field information on the sky. The values contained within the class are all kept in degrees. Properties are exposed that present those values in radians.

fid

int – The field’s ID.

fov

float – The field’s field-of-view.

ra

float – The field’s right ascension.

dec

float – The field’s declination.

gl

float – The field’s galactic latitude.

gb

float – The field’s galactic longitude.

el

float – The field’s ecliptic latitude.

eb

float – The field’s ecliptic longitude.

Initialize the class.

Note

All angular values are expected to be in degrees!

Parameters:

• fid (int) – The field’s ID.
• fov (float) – The field’s field-of-view.
• ra (float) – The field’s right ascension.
• dec (float) – The field’s declination.
• gl (float) – The field’s galactic latitude.
• gb (float) – The field’s galactic longitude.
• el (float) – The field’s ecliptic latitude.
• eb (float) – The field’s ecliptic longitude.
