This directory contains prototypes for scripts that may be called by the camera driver. Copy appropriately edited versions to /usr/local/bin in the search path for the server. The ccd driver executes transfer_image to send a fits image to a remote observer. Edit the script to have the appropriate address. The script set_camera_filter should take a filter number as an argument and send a command to a filter wheel. The SBIG filter wheel is supported internally and does not use this script. If you have another filter wheel, then a script such as this would allow you to use XmCCD to control the filter wheel. An executable for the Optec IFW3 filter wheel is provided. Simply "make" the routine in the ifw directory, and then "make install". This will provide a softlink for "set_camera_filter" pointing to setifw. The script would only be needed if you use another filterwheel and you have software that can be adapted to this use. If ccd_process is invoked, it can call other operations to be done after an exposure is completed. These may include running the guide script, and a dome track script, followed by starting another exposure.
