Viewing files generated by Arroyo
One important feature of the arroyo libraries is that they generate
files in fits format. There is a file format for nearly every class.
Some of these classes contain fits image data - others contain only
fits header keyval pairs.
One useful program included in the source distribution is simhdr.
This program prints out fits header information for any file generated
by arroyo. This includes information on the type of file.
You can look at files that contain 2d fits image data using a fits
viewer like ds9 .
The most useful things to view at this stage in development are
refractive atmospheric layers and diffractive wavefronts. The former
are 2d images of the OPD variations arising in the turbulent
atmosphere. Refractive atmospheric layers contain a single 2d fits
image, which may be viewed using
ds9 file.fits
Files containing diffractive wavefronts are composed of two 2d fits
images. The first image stores the amplitudes (e.g. the square root
of the intensities) and the second image stores the phases. You may
look at the amplitudes using
ds9 file.fits
and the phases using
ds9 file.fits[1]
In the future I anticipate writing an observation class, in which will
be stored a 2d image of the intensities. Instances of this class will
be read out from the as-yet-to-be-written detector class.
