PI and CoI, Observer
Associated with each proposal is a Principal Investigator
(PI) and, optionally, a Co-Investigator/Observer (CoI/O). If there is no
CoI/O, the PI is the Observer.
- The Observer is the person who is responsible for the
observation parameters and with whom User Support works to ensure a
correct observation specification.
- E-mail notification of the data being ready for
download is sent to the PI and the CoI/O. If hard medium distribution
is requested, the medium is sent to the PI.
- Change of CoI/O: a request for changing the CoI/O has
to come from the PI by e-mail and be directed to the Director's Office
. (Note that a CoI/O can only be assigned per proposal, not on
the basis of an individual ObsId.)
Procedures and Policies
Proprietary data are distributed through
WebChaSeR and on
physical media. Data products generated by Automated Processing first
have to go through Verification and Validation. The
Principal Investigator and the
Co-Investigator/Observer will then be notified
that the data are available through WebChaSeR; at the same time a copy is
made on physical medium, if requested, that is mailed to the PI only.
Products generated by Custom Processing also go through V&V but are
only distributed through the ftp site. In all
cases the tar file contains a Standard Data Distribution.
Access to proprietary data (i.e., the proprietary products associated
with proprietary observations) is restricted to two accounts: a PI
account (that provides access to all proprietary observations of the
PI) and a proposal account (that provides access to all proprietary
data associated with a particular proposal and that the PI may want
to share with collaborators). The Data Distribution e-mail
notification contains a reminder about the latter account.
The staging procedures for data retrieved from the CDA include the use
of hidden directories to protect the potentially proprietary nature of
the data. This mechanism is effective but requires the user to enter
the full path or URL, rather than meandering through the ftp directory
structure. The only situation where this might cause a problem is
when users employ Safari as their web browser; we recommend
switching web browsers in that case.
