Class DitherProduct

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

(inherited documentation)

Close image handle for each member.

Overrides: pattern.Pattern.closeHandle

Create Exposure object for meta-chip product after applying distortion model to input members.

Overrides: pattern.Pattern.buildProduct

(inherited documentation)

This method will rely on final product's 'rd2xy' method to compute offsets between the different input chips.

Overrides: pattern.Pattern.computeOffsets

Add up the exposure time for all the members in the pattern, since 'drizzle' doesn't have the necessary information to correctly set this itself.

Overrides: pattern.Pattern.getExptime

For each entry in prodlist, append the appropriate type of Observation to the members list.

If it's a moving target observation apply the wcs of the first observation to all other observations.

Overrides: pattern.Pattern.addMembers

Return the class instance for the member with name memname.

Overrides: pattern.Pattern.getMember

Returns a dictionary with one key for each member. The value for each key is a list of all the extension/chip names that make up each member. Output: {member1:[extname1,extname2,...],...}

Overrides: pattern.Pattern.getMemberNames

This method would build a list of parameters to run 'drizzle'
one a single input image.
   The reference image info 'ref' will be passed as a SkyField object.
   The default output reference frame will be passed as 'def_wcs'
   for comparison to the user's selected object 'ref'.

Overrides: pattern.Pattern.buildPars

(inherited documentation)

This method combines the results of the member's buildMetachip() methods into a composite WCS. (DitherProduct method)
