Converse of object

• perform: In both modes the user may perform photometry using either the traditional aperture method or using optimal extraction.

• use: The source counts and their errors were calculated using circular aperture photometry centered at the listed source position.

• center: The source counts and their errors were calculated using circular aperture photometry centered at the listed source position.

• do: What manuals are available for helping me do photometry?

• mean: CONST means that photometry has been obtained but no wave has been observed.

Adjective modifier

• accurate: Accurate photometry will rarely be possible through the narrow slits.

• differential: Differential temporal photometry: Transit durations are a few hours to less than a day.

• circular: The source counts and their errors were calculated using circular aperture photometry centered at the listed source position.

• relative: The photometry in Pix_M9 is simple ' relative photometry ' and will not automatically give you the magnitude of a star.

• photoelectric: Some entries are from photoelectric aperture photometry or from CCD photometry with the Whipple Observatory 24 inch.

• stellar: They treated the raw model colors in the same manner as raw stellar photometry.

Preposition: on

• image: This was found to be more robust than aperture photometry on the images.

Modifies a noun

• observation: Description: This recipe reduces a " bright standard " photometry observation observed through one or more filters.

• package: A specialist photometry package should be used if accuracy, rather than speed, is paramount.

• result: Addition of FWHM to the aperture photometry results and small text list.

Preposition: of

• source: Photometry of each source was estimated from the brightest pixel not affected by glitches.

Noun used with modifier

• aperture: For instance, you might wish to change the aperture diameter for the aperture photometry.

• surface: Surface photometry has also been carried out on all the targets of the 2dF Galaxy Redshift Survey using digitized UK Schmidt Telescope data.

• multi-colour: Hence we also determine the composition of these bodies through multi-colour photometry, to assist theoretical models in disentangling the possibles sources of NEOs.

• imaging: Much of the imaging photometry is expected to be complete by the end of 2006.
