HeaderService

Development for LSST Meta-data FITS header service

Description

This is the development for the LSST Meta-data FITS header client. It uses a set of FITS header library templates and DDS/SAL Python-based communication layer to populate meta-data and command the header client to write header files.

Requirements

• numpy
• fitsio (https://github.com/esheldon/fitsio)
• Python DDS/SAL libraries
• OpenSplice compiled binaries for centOS7
• A CentOS7 VM or docker container

Examples

# Setup the path for the HeaderService
source HeaderService/setpath.sh  ~/HeaderService 

# Initialize header client (Terminal 1)
header_client_threaded

# Send telemetry to trigger header writing (Terminal 2)
telemetry_sim_single --ra 21.723 --dec -45.127 --band g --visitID 1
telemetry_sim_single --ra 22.127 --dec -46.890 --band r --visitID 2
telemetry_sim_single --ra 22.127 --dec -46.890 --band i --visitID 3
