TIPTOPbase is a public, interactive database service implemented to access the atomic data
computed in the international collaborations referred to as the
Opacity Project (OP) and the
IRON Project (IP).
It is the upgrade of the TOPbase facility that was originally installed at CDS in 1993.
The following databases and interactive servers are currently offered:
Complete package (data, codes and instructions) to compute
mean opacities and accelerations is now available. It contains improved opacities and a
suite of versatile, easy-to-use codes. Download from
Opacity Project home page.
- TOPbase: on-line interactive database
containing LS atomic data (energy levels, f-values and
photoionisation cross sections) computed in the OP
- TIPbase: online interactive database
containing fine-structure atomic data (energy levels, A-values and
electron impact excitation collision strengths and rates) computed in the IP
An interactive server for online computing of opacities for arbitrary
chemical mixtures. Data and codes have been updated with the release OPCD_2.0 (01-12-04).
