| Abstract: |
Gemini's Recipe System has been in development for many years. This
pipeline infrastructure has reached a maturation level that allows us
to start sharing the software with external developers to get feedback
and new ideas. The principles at the core of the Gemini's Recipe
System are: (1) the infrastructure is "instrument-agnostic" and
supports several instruments; (2) the reduction sequence dynamically
adjusts to the data during processing; (3) the infrastructure must work
in different reduction contexts, for example, nighttime quality
assessment, desktop user scientific reduction, quick look reduction,
etc. With a few exceptions, pipelines are generally developed in a
static configuration and aim to reduce one type of data. Instead, our
model maximizes code re-use and when a new instrument is delivered,
will expedite the development of data reduction suite for that
instrument since most of the pieces will already be in place. The
differences in data from various instruments are kept in configuration
packages rather than in the data reduction algorithms or the
infrastructure. Here we present the general functional principles of
the Gemini's Recipe System and some practical examples of how it can be used. |
