Subsections

Synthesis

Priorities

Scientific completeness: This remains the primary driver in synthesis development. Significant synthesis capabilities exist within the package at present, and are being more widely used in the scientific community with each release. This process can be aided by continued improvement in vertical integration of synthesis applications, and in the addition of scientific completeness beyond current capabilities.
Time-critical local priorities: It is important that the project meet time-critical targets required for successful AIPS++ use at consortia sites, particularly where the use of AIPS++ is closely integrated into the critical path required for instrument use or operation.
Basic automated imaging: Significant work in this area took place in v1.4, but needs to continue in this development cycle to include the highest level tools in this area.
Automated testing: Expanding the automated testing of synthesis capabilities using simulated data is a priority during this cycle, both at the C++ and Glish level. This has benefits in speeding up release testing, and in daily and weekly checks of system integrity for end-users and user test groups.
