Package multidrizzle

source code

MultiDrizzle combines astronomical images while removing distortion and cosmic-rays. The Python syntax for using MultiDrizzle relies on initializing a MultiDrizzle object, building up the parameters necessary for combining the images, then performing the actual processing necessary to generate the final product. The process starts with the input of the image names to initialize the MultiDrizzle object:

>>> import multidrizzle
>>> md = multidrizzle.MultiDrizzle(input,'other parameters')
>>> md.build()
>>> md.run()

MultiDrizzle defines default values for all inputs, and only those values which need to be over-ridden should be entered.

Further help can be obtained interactively using: >>> md.help()

_splitNsigma(s)

source code 

Purpose

This is a help function that is used to split up the "combine_nsigma" string. If a second value is specified, then this will be used later in "minmed" where a second-iteration rejection is done. Typically the second value should be around 3 sigma, while the first can be much higher.
