| Abstract: |
The Herschel Common Science System (HCSS) is a substantial Java software package, accompanying the development of the
Herschel Mission, supporting all of its
phases.
In particular, the reduction of data from the scientific instruments
for instrument checkout, calibration, and astronomical analysis is one
of its major applications. The data reduction software is split up into
modules, called “tasks”.
Agreed-upon sequences of tasks form pipelines that deliver well
defined standard products for storage in a web-accessible Herschel
Science Archive (HSA). However, as
astronomers and instrument scientists continue to characterize
instrumental effects, astronomers already need to publish scientific
results and may not have the time to acquire a sufficiently deep
understanding of the system to apply necessary fixes. There is a need
for intermediate level analysis tools that offer more flexibility than
rigid pipelines.
The task framework within the HCSS and the highly versatile Herschel
Interactive Processing Environment (HIPE), together with the rich set
of libraries provide the necessary tools to develop GUI-based
interactive analysis packages for the Herschel instruments.
The SPIRE Photometer Interactive Analysis (SPIA) package,
described in this paper, proves the validity of the concept for
the SPIRE instrument, breaking up the
pipeline reduction into logical components, making all relevant
processing parameters available in GUIs, and providing a more
controlled and user-friendly access to the complexities of the
system. |
