Getting Started

ccdproc

ccdproc is a module that allows for CCD image calibration and reduction. The main functions are:

• ccdproc(): CCD calibration.

• ccdlist(): Get information on FITS images.

• masterbias(): Make a master bias frame.

• masterdark(): Make a master dark frame.

• masterflat(): Make a master flat frame.

• makebpm(): Make a bad pixel mask image.

• autored(): Automatically pick up new images and reduce them.

• redrun(): Automatically reduce a set of images. (in development)

phot

phot is a module that has a number of photometry routines.

• background(): Estimate the smooth background in an image.

• detection(): Detect sources in an image.

• daodetect(): DAO source detection.

• aperphot(): Perform circular aperture photometry on image.

• morphology(): Calculate centroids and morphology of sources.

spec

spec is a module that has a number of spectroscopy routines.

• trace(): Trace the position and width of a spectrum.

• boxcar(): Boxcar extract a spectrum.

• extract(): Extract spectrum using Gaussian fits.

• emissionlines(): Detect peaks in comparison lamp spectra and fit Gaussians to them.

• gaussfit(): Fit a single Gaussian to data.

• matchlines(): Match two lists of wavelengths.

• continuum(): Calculate the continuum of a spectrum.

• ccorrelate(): Cross-correlate two spectra.
