IRAF Programs


Script Name Description Needed tasks

autored.cl

Automatic calibration of images, for one night.
Steps: Changeing the image name  Convert images to IRAF or fits format  Subtract Bias  Correct by Flat Field  invert images

autoredn.cl

Multi-night Automatic calibration of images.
Steps: (see autored.cl)

autored.cl

autoast.cl


Astrometry Page
Autoast.cl & Intast.cl
Automatically find astrometric solution of an images, write WCS to the header and convert plate position to R.A., Dec (or vise versa), the program can converge even if the initial guess coordinates are in error larger then the field of view.
Steps: find stars in each image

intast.cl


Astrometry Page
Autoast.cl & Intast.cl
Automatically find astrometric solution of an images, write WCS to the header and convert plate position to R.A., Dec (or vise versa), the program can converge even if the initial guess coordinates are has error, larger then the field of view! - Interactive version, click object to measure with mouse. In the current version the program can work with the USNO AA2.0 or USNO SA1.0/SA2.0 catalogue
Steps: find stars in each image

autodaofind.cl

Automatic star finding in an image, using daofind
Steps: Find sky sigma  Run daofind

autodaophot.cl

Automatic photometry of all the stars found in a image, using daofind/daophot
Steps: call autodaofind  select PSF stars (1/2 iterations) running daophot (1/2 iterations)
autodaofind.cl

autoaperphot.cl

Automatic photometry of all the stars found in a image, using daofind/daophot
Steps: call autodaofind  running phot
autodaofind.cl

find_image_size.cl

Find image size in pixels
Steps: read the header for image size

autoalign.cl

Automatically aligned images, the program can converge even if the shift between the images is VERY large (~50%)
Steps: find stars in each image  call pgshift (Originaly written by Uri Givon) for find the shift between two lists.  align images
autodaofind.cl

usno_cd.cl

Find USNO A1.0/2.0 disk number. Steps:

fast_phot.cl

Preliminary Version!
Fast/on-line aperture photometry. Steps:  FastPhot Home Page

ebv_extin.cl

Preliminary Version!
Extract E(B-V) values from Schlegel, Finkbeiner & Davis (1998) Dust IR maps. Steps: read fits image and get value for each galactic coordinate in list  Retrieve the Schlegel et al. E(B-V) 40962 maps from: http://www.astro.princeton.edu/~schlegel/dust/data/data.html
