naco_img_zpoint.param.star_r = 2.0
naco_img_zpoint.param.bg_r1 = 2.0
naco_img_zpoint.param.bg_r2 = 3.0
naco_img_zpoint.param.ra = 999.0
naco_img_zpoint.param.dec = 999.0
naco_img_zpoint.param.pscale = -1.0
naco_img_zpoint.param.mag = 99.0
naco_img_zpoint.param.sx = 10
naco_img_zpoint.param.sy = 10
naco_img_zpoint.param.check_im = False

You may also set or overwrite some or all parameters by the recipe parameter param, as shown in the following example:

import cpl
naco_img_zpoint = cpl.Recipe("naco_img_zpoint")
[...]
res = naco_img_zpoint( ..., param = {"star_r":2.0, "bg_r1":2.0})
