The Ca HK and Guide Camera sub-FITS will be created on the KPF FIU computer (an ASL Lancelot located within the K1 server room). This computer must NFS mount the /data/ partition from kpf-asl-prime to use that file system for writing out the data. That said, as long the kpf-asl-prime has access to the KPF FIU computer’s filesystem and the dispatchers broadcast through a keyword the location of the file output, the L0 assembler could find the files.

FITS Header Keyword Construction
The assembler will need to pull data from two different sources to construct the final primary header. The first are the individual FITS files themselves. The second source of data are values from various other subsystems that are broadcast as keywords during the exposure.
