[REVIEW]: spike: A tool to drizzle HST, JWST, and Roman point spread functions for improved analyses

In the field of astronomy, analyzing data from space-based telescopes such as the Hubble Space Telescope (HST), James Webb Space Telescope (JWST), and the upcoming Roman Space Telescope is crucial for understanding the universe. However, the point spread functions (PSFs) of these telescopes can significantly impact the accuracy of these analyses. Ava Polzin has developed a tool called spike, which aims to improve the analysis of astronomical data by providing a way to drizzle HST, JWST, and Roman PSFs. In this review, we will examine the spike tool and its capabilities.

What is spike?

spike is a Python package designed to drizzle PSFs from HST, JWST, and Roman onto images. This process involves convolving the PSFs with the images to simulate the effects of the telescope's optics. The tool is built on top of the Astropy library and uses the NumPy and SciPy packages for numerical computations. Ava Polzin has made the spike tool available on GitHub, allowing users to easily install and use it in their research.

Features of spike

The spike tool offers several features that make it a valuable resource for astronomers:

  • Drizzling PSFs: spike allows users to drizzle PSFs from HST, JWST, and Roman onto images, providing a more accurate representation of the telescope's optics.
  • Support for multiple telescopes: The tool supports PSFs from multiple telescopes, including HST, JWST, and Roman, making it a versatile tool for astronomers.
  • Easy installation: spike is available on GitHub, making it easy to install and use in research projects.
  • Well-documented code: The spike code is well-documented, making it easy for users to understand and modify the tool to suit their needs.

Benefits of using spike

Using spike can have several benefits for astronomers:

  • Improved accuracy: By drizzling PSFs onto images, spike provides a more accurate representation of the telescope's optics, leading to more accurate analyses.
  • Increased flexibility: The tool's support for multiple telescopes and easy installation make it a versatile tool for astronomers.
  • Community support: The spike tool is available on GitHub, allowing users to contribute to the development of the tool and receive support from the community.

  1. Install spike: Users can install spike using pip: pip install spike
  2. Import spike: Users can import spike into their Python scripts using import spike
  3. Drizzle PSFs: Users can drizzle PSFs onto images using the spike.drizzle function

In conclusion, spike is a valuable tool for astronomers that provides a way to drizzle PSFs from HST, JWST, and Roman onto images. The tool's features, including support for multiple telescopes and easy installation, make it a versatile tool for researchers. By using spike, astronomers can improve the accuracy of their analyses and increase their flexibility when working with astronomical data.

Future developments

The future development of spike is exciting, with several potential features on the horizon:
