LCFUNF

Name

lcfunf

Purpose

Compute a lightcurve function independent variables.

Description

This is to be used in cases where you already know the fundamental period.
The input independent variable is assumed to be reduced to phase of a
fundamental period already. The integer part of the number is not used
by the function.

Calling Sequence

ans = lcfunf(x,m)

Inputs

x - independent variable (longitude, between 0 and 360)
m - order of fit (see lcfun.pro)

Optional Input Parameters

PHANG - phase angle of each observation, will be saved to common, if
not provided will use the last values saved to common block.
Angle is in degrees.

Keyword Input Parameters

Outputs

return value - 2-d array with all the independent variables computed.
This is normally used to setup a svdfit or similar
operation.

Keyword Output Parameters

Common Blocks

lc_com - one variable, phang, that is used to save the phase angle from
one call to the next in case of calling the lcfun or lcfunf
from a canned routine that cannot be taught to pass the
extra independent variable.
