Background
The keck.lris IRAF package includes several tasks to
help observers complete LRIS slitmask alignment and reduce and
analyze LRIS images. Due to the new multi-HDU
image format introduced in the June 2009 LRIS-Red Upgrade Project,
the package was completely revamped.
New and Revised Tasks
- cdata
- generalized to call "lrisserver" instead of "punaluu"
- multi2simple
- new task which can convert from mHDU to "flat" image format
- lrisdisplay
- new task to display mHDU LRIS images in ds9 under IRAF
- lspecfocus
- now supports both flat and mHDU images. Also permits
dividing the image into multiple sections in the dispersion
direction in order to check focus variation in the wavelength
axis.
- check_boxes
- now supports mHDU images and calls lbox
- do_check_boxes
