Method

Select the method for making the dark correction:

Direct applies the dark reference frame by direct subtraction, with no adjustment such as time-scaling.

Time scaled adjusts the dark reference frame to match the time that dark count accrued in the flat frames. This is usually the best method.

Optimized attempts tp optimize the correction by minimizing the noise in the final image. This method does not usually give the est result unless the noise is quite high, which is not too common using modern image sensors.

Darktime Keyword

When the Time scaled method is selected, this field specifies the header keyword that chaacterizes the dark (thermal) exposure time of the dark frame and flat frames. Usually this is EXPTIME or DARKTIME.
