| catalogue | The input catalogue |
| minsize | The minimum size in pixels of objects to be used in the analysis |
- Returns
- CPL_ERROR_CODE if everything is OK, the concrete error in other case
Description: The information in an catalogue is scanned and each object is classified based on a number of shape criteria.
- Note
- QC headers: The following QC parameters are read from the catalogue extension.
- MEAN_SKY: The mean sky found by catalogue.
- SKY_NOISE: The sky noise found by catalogue. The following QC parameters are written to the catalogue extension.
- IMAGE_SIZE: The average FWHM of stellar objects in the catalogue
- ELLIPTICITY: The average stellar ellipticity.
- POSANG: The average position angle on the image.
- APERTURE_CORR: The aperture correction for an aperture with a radius of Rcore.
- NOISE_OBJ: The number of noise objects detected on the image
-
DRS headers: The following DRS parameters are read from the catalogue extension.
- THRESHOL: The detection threshold used by catalogue
- RCORE: The core radius used by catalogue
- SEEING: The averaged seeing found by catalogue
- NXOUT: The number of pixels in a row of the original image
- NYOUT: The number of pixels in a column of the original image The following DRS parameters are written to the catalogue extension
- CLASSIFD: Set if the catalogue has been classified
