Subdirectory cf contains the configuration files used by the indexing daemon skyd.py (which passes it to skyd_wait.py). Subdirectory report is the directory where skyd_orbit.py (running remotely or locally) write the report files used by skyd_wait.py to keep track of things. Both cf and report need to be accessible, with read/write access, to all machines controlled by the indexing daemon. Subdirectory log is where the indexing daemon writes its logfile Subdirectory run is where the indexing daemon writes its pid file Subdirectory list contains a number of catalogues for the SMEI data. Among these are the catalogues created by the IDL program skyd_cat.pro and updated by the indexing daemon. Subdirectory at contains a single file .forward. This contains a valid email address (usually the address of the account running the SKYD daemon, e.g. skyd@zardoz). If a soft link is created on each of the machine controlled by the daemon with ln -s /cat/at/.forward then the batch program at will forward email of completed runs to this account. This is used to accumulate results in a central location.
