BTW, those costs are dropping. "List price" for a commercial Titan launch is $125M. With a payload of 33,000 pounds this comes to $3788/pound. This price should drop because 1) the above quoted price is list so I'm sure you can negotiate a discount and 2) the USAF just ordered a hundred Titan IV's which should reduce costs (both are made on the same line).

Some of the pictures have made it into TV news and newspapers. The word seems to be slowly spreading that HST is a very good telescope after all, and that it can most likely be fixed. I think NASA generated a lot of trouble for itself by releasing certain premature conclusions. That might have been a good time to hedge claims, and say "we'll have a more definitive answer in a few days". Incidentally, I just heard a claim that the tradition of covering space missions on television was somewhat related to the game show scandals.

After resubscribing (to SPACE-L at FINHUTC), the double sending of the space digest started again. As an example of this, I copied the mailheader of a todays double sended issue above. I have no solution for this problem, but it seems to me that there is some wrong entry in some forwarding list (I never sent anything to NETNEWS at TREARN). Thanks a lot, Gunnar ------------------------------ Date: Mon, 22 Oct 90 12:42:16 EDT From: JW_GOODR@UNHH.Bitnet Apparently-To: Mr. Baalke; I thank you very much for your excellent periodic postings on the Spacenet of the doings of JPL. I wonder if it is possible to receive these updates without having to deal with the rest of the postings on the net. I am an undergrad with a limited amount of mem-space, and I am mostly interested in the postings concerning the spacecraft. Could you possibly send the messages directly to me or direct me to a board that you send these posts to that has less arguements? Thank you for your time...

One possible measure of productivity might be the total man-hours required to get from raw materials (i.e. ore in the ground) to finished (and installed) product (i.e. payload in orbit). I think the consensus was that while Soviet workers seem to be less productive than American workers in general, space launches are one of the things they do relatively well, and that this, coupled with lower labor costs, permits them to launch for a lower price per pound of payload.

But let me tell you about two possible hints I have. 1) If you have images of your spectra and if you could transform them into FITS format, than the Program PCVISTA from might be a help for you. It was described in PASP about one year ago (between September and November I think, I could look up the citation if you need it; just remembered, one of the authors is called M. Richmon PCVISTA provides all neccessary programs to reduce CCD-images in FITS format. Also lots of routines to do photometry of stellar objects or extended objects are supplied. It comes even with a program to display 1-D Data (graphs, tables) and a hardcopy routine. This latter program is a subset of MONGO. Some of PCVISTA's weaknesses: It uses only EGA resolution, there are no routines to analyze spectras (you have to provide them for yourself) and is distributed as source code which must be compiled with MS-C. I use the program on a 286-clone with trident-vga (256kb) without any problems since early this year. 2) If you need only a graphice program to display your spectra, then you might try out AUTOGRAF, OR GNUPLOT2, which are two 1-D display programs in SHAREWARE. Both are available via FTP from simtel20 or wuarchive.wustl.edu. Becasue both are of general nature, they lack the ability to analyse spectra, too. 3) I forgot to mention MIDAS, which is a image/spectra analysing and display program, develop and distributed by ESO. But I am not shure whether they developed a PC-version yet (also you sometimes here such rumors). Hope I could help you. In case of further questions, drop me a note.
