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.
CATEGORY:
Mathematical
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.
