[udf-dlm-develop] present status

[Harald F. <hf...@ap...>]

Hi everybody,

I thought I should give you a short status report after some days of programming 
with the dlm interface.

1. So far we can read all but two UDF-files for FUV. One of them does not 
contain reasonable data, so it's a file problem. For the other file we get an 
error message 

IDL>   fh  = UDF_Open(key, start_time, end_time, _Extra=_e )
% UDF_OPEN: Unrecognized sensor type, 16

At the moment I don't know if it is a problem with the file or with DLM. Did 
anybody see a similar thing?

2. I'm still in the process of cross-checking, but the data which I can read are 
fine and the same as we expect from our level-zero data.

3. Every data structure contains the two fields

   START_AZ        FLOAT           0.00000
   STOP_AZ         FLOAT           1.00000    (or other number like -2801.27)

It doesn't bother me, I'm just wondering where these data come from, because 
these data are definitely not in our FUV files. 

4. When I read our WIC, SI12 and SI13 files I always get a

IDL>     d = udf_read(fh)
% Program caused arithmetic error: Floating overflow

Is it just a coincidence that these three files contain matrix data, and all 
other files don't? 

So far from here,
Harald
