I produced 24 GIF images yesterday on the IRIS. They are named i1.gif thru
i24.gif . The first two are first light images, the 30 second image, and the
second is the side by side with the Las Campanas image. The resolution is
about 640X480X256. The other 22 are pre-launch, launch, deploy, some earth
shots and two landing shots.
The images are available via anon ftp from IRIS.UCIS.DAL.CA in /Pub/Gif .
The machine had a frame grabber to make these from RGB format and a program
that converted them to gif. It had no other controls except for managing
contrast, brightness, hue and saturation. The quality is not bad considering
it came from video tape off of an 8 foot satellite dish. I am in a fringe
zone for SATCOM, so you will see the noise.
I will not be able to do any other image conversion, since the University is
giving the machine back to SGI on Thursday, but I will try to do some others
for people of the close encounter images I have of Voyager last summer. I have
about 35 hours of tape of these images, and the quality is about the same, but
b&w may be a touch better.
The files add up to be about 2 Mb in size, so mailing is impractical, but if
you send me a disk, I will put them on and send it back. I would also like
some comment on what you all think.
Cheers..
