__VERSION__="1.1.1 - 2021 Dec 03 - 2023 jul 14"

__DESCRIPTION__="""

M.Maris

first version of order 0 Pointing Reconstruction Model (PRM)

order 0 Pointing Reconstruction Model (PRM)

=========================

#Example:

from lspe_prm import PRM0

# instantiate object as an ideal telescope setup

prm=PRM0(Ideal=True)

# set some angles

prm.tiltFor = 0.1 # deg

prm.cphi0   = -5.1 # deg

prm.commit() # this is mandatory

# creates a list of [theta, phi] couples (deg)

theta_phi=np.array([

 [15., 20]

 ,[25., 50]

 ,[35., 30]

])

#creates the list of pointing matrices

RotMatr=prm(theta_phi)

#to recover pointings makes dot product with (0,0,1) vector

Pointing=np.array([k.dot(np.array([0,0,1])) for k in RotMatr]).T

=========================
