Do you know how to create a flat (purely random) distribution of stars using Stuff? The parameter STARCOUNT_SLOPE is a log scale. I have tried to plug in zero and very low values (<0.001) , but I recieve the error STARCOUNT_SLOPE keyword out of range, and Skymaker doesn't run. Slightly higher values (<0.1) cause SExtractor to have a hard time detecting the stars: it detects few stars and has a lot of flags on each. Using different reliable numbers, the log scale doesn't seem to change.
You must be refering to SkyMaker, not Stuff? Thanks for this notice. I will have a look at it in the coming days.

Actually the reason for the limitation is that in SkyMaker the STARCOUNT_ZP parameter sets the cumulated number of stars brighter than the second MAG_LIMITS argument value, irrespective of the first MAG_LIMITS argument value. In other words, STARCOUNT_ZP represents the total number of stars with magnitudes between -infinite and the second MAG_LIMITS. Hence allowing a STARCOUNT_SLOPE of 0 would require an infinite STARCOUNT_ZP for generating a non-zero number of stars per magnitude interval.

where i can get tutorial for the stuff?
