This task applies a headerlet to a science observation to update either the
PRIMARY WCS or to add it as an alternate WCS.

filename = ""
hdrlet = ""
attach = True
primary = True
archive = True
force = False
wcskey = ""
wcsname = ""
verbose = False

Parameters
----------
filename: string, @-file or wild-card name
         File name(s) of science observation whose WCS solution will be updated
hdrlet: string, @-file or wild-card name
         Headerlet file(s), must match input filenames 1-to-1
attach: boolean
        True (default): append headerlet to FITS file as a new extension.
primary: boolean
        Specify whether or not to replace PRIMARY WCS with WCS from headerlet.
archive: boolean
        True (default): before updating, create a headerlet with the
        WCS old solution.
force: boolean
        If True, this will cause the headerlet to replace the current PRIMARY
        WCS even if it has a different distortion model. [Default: False]
wcskey: string
      Key value (A-Z, except O) for this alternate WCS
      If None, the next available key will be used
wcsname: string
      Name to be assigned to this alternate WCS
      WCSNAME is a required keyword in a Headerlet but this allows the
      user to change it as desired.
logging: boolean
        enable file logging
