e2e - Module

Postscript file available

Module for End-to-end processing
include "e2e.g"



Description

This is experimental and under rapid development: please do not use!

The NRAO End-to-End project (e2e) has the goal of providing end-to-end processing of data from telescopes. This is being developed for NRAO telescopes (VLA, VLBA, GBT, EVLA), but is being designed for general use.

The e2e module implements two inter-related services.

An archive
A repository for observations from telescopes, and for pipeline-processed results.
A pipeline
A facility for processing data from specific projects in the archive, and inserting processed results in the archive.

These services are designed to be used both from within AIPS++ and from the web.

An overview of the tools:

e2ecatalogs
is responsible for constructing and accessing catalogs.
e2epipeline
is responsible for constructing and executing scripts to process data.
e2epipelinequery
is responsible for serving queries to e2epipeline.
e2emakefiles
contains the various Glish makefiles that process data.
e2estandards
is responsible for specifying standard values to be used in processing (e.g. cellsizes, image sizes, solution intervals, etc.).
e2epublish
is responsible for publishing results to a standard location, as FITS files, and with information web pages.
e2emsutils
has utility helper functions for MeasurementSet access.
e2eimagingutils
has utility helper functions for imaging.
e2edisplayutils
has utility helper functions for display.
e2epipelineutils
has utility helper functions for the pipeline.
e2echromepipe
connects glish to a web server.

This module uses a standard directory layout, rooted at the environmental variable E2EROOT. This allows various and mirrored copies of archives to be used. However, the subdirectory structure must be as expected.

archive
Archive root
archive/catalogs
Catalogs
archive/catalogs/TELESCOPE
Catalogs for telescope TELESCOPE
archive/data
Original (and untouched) data
archive/data/TELESCOPE
Data for telescope TELESCOPE. This directory and below have telescope-dependent contents to reflect the differing nature of data from various telescopes.
archive/data/VLA/tapes
Data tape images for the VLA.
archive/results
Results from processing
archive/results/projects
Results from processing for projects
archive/results/projects/PROJECT
Results from processing for project PROJECT. All results must be indexed by a file PROJECT.html or PROJECT.xml.
archive/results/calibrators
Calibrator source list
processing
Processing area root. This has little substructure as yet.
