Andicam Optical & Near-Infrared Photometry Pipeline For Point-like Sources
This respository contains two pipelines for point source photometry on CCD images from the ANDICAM instrument mounted on the CTIO 1.3m telescope (DePoy et al. 2003).
SMARTSOpt.py - The optical photometry module
SMARTSIR.py - The near-infrared photometry module
SOptfull.py - The wrapper for the optical photometry
SIRfull.py - The wrapper for the near-infrared photometry
Prerequisites
Before using the pipeline, you need to install the following python packages: os, glob, string, linecache, subprocess, numpy, pandas, pyraf, astropy, alipy. To install them with pip:
pip install os, glob, string, linecache, subprocess, numpy, pandas, pyraf, astropy, alipy
You will also need the "daophot" stellar photometry package of Peter B. Stetson if you wanna do psf-photometry. This package is only available by its developer upon request after signing an agreement.
Steps for the optical photometry
- Gather the images into a directory.
- Align the images with respect to a reference frame.
- Do the photometry
- Collect the photometry results
Steps for the infrared photometry
- Gather the images into a directory
- Process the dithered images (make a sky noise image, denoise each of the dithered images, and then align and combine them to amplify the signal)
- Align the combined images with respect to ta reference frame
- Do the photometry
- Collect the photometry results
