Writing grid file with editor

[tbaehnck]

Hi all,

 

I'd like to write me a grib file with three stars with the same

same dec, like the Polaralign grib already is in sequence. I just want to have smaller distances between the stars because if I use a long focal length with my small chip, the polaralign with the laser is sometimes not accurate enough to solve the third plate.

 

How I have to interpret the numbers in a grib file, so that I can write my own with the stars in same dec?
