photometric

For each photometric system a set of primary standard stars is provided.

Photometric observations made in 1987 gave a rotation period of either 6.78 or 5.4 hours.

Photometric measurements reported in 1982 gave a rotation period of 8.452 hours.

Many different units of measure are used for photometric measurements.

It provides the possibility to relate these two photometric systems.

At present, there are more than 200 photometric systems.

All photometric data is available through a web interface within 5 minutes after exposure.

Multiple photometric studies of this asteroid were performed between 1969 and 2003.

Photometric observations indicate that its surface is made of water ice.

A photometric study in 2001 was unable to find a definite period of rotation.

More complex forms of photometric measurement are used frequently within the lighting industry.

In 1877 he began making photometric observations of the planets and their atmospheres.

This is a type of star that is a close photometric match to the Sun.

However, its photometric properties indicate that it may instead be an interloper.

Photometric systems usually use a single camera, but take multiple images under varying lighting conditions.

For the same film speed, the accumulated photometric exposure (H) should be similar in both cases.

It could take up to 100,000 measurements per second with a photometric accuracy of about 2% or better.

The photometer measured in the 7 band Geneva photometric system.

The large database of photometric measurements will give the opportunity for studying variable stars.

In 1967, the 12 inch telescope at the observatory made its last professional photometric observations.

The camera must also be able to integrate the image for at least 5 to 10 seconds, with a minimum photometric resolution of 8 bit.

It is the first known standardized photoelectric photometric system.

Photometric stereo, a computer vision technique also known as "shape from shading"

The sphere creates a reference radiation source that can be used to provide a photometric standard.

The set of passbands or filters is called a photometric system.
