Hi Han,

When I was doing some tests of the linearity of my camera I found a small bug in Astap.
In fact, it seems the exposure time is only the integer part of the exposure : e.g. 22.25s becomes 22s

Example in annex

Groetjes,
Pieter.

Hello Pieter,

This was done by purpose. Below 10 seconds exposure time you get fractions of of seconds. Above 10 seconds the values are rounded. The idea was to make them better comparable. So a 50 seconds light matches with a 50 seconds dark but also with a 50.1 seconds dark.

The same is done for the temperature.

Han
