The Python Satellite Data Analysis Toolkit (pysat) provides a simple and flexible interface for robust data analysis from beginning to end - including downloading, loading, cleaning, managing, processing, and analyzing data. Pysat's plug-in design allows analysis support for any data, including user provided data sets.

H5plot is a small GUI to view the solutions in an H5parm interactively. It is a spiritual successor to ParmDBplot for quickly reviewing gain solutions generated by NDPPP.

LePHARE is a code for estimating galaxy redshifts and physical parameters using template fitting.

This package provides a wide variety of utilities, focused primarily on numerical python, statistics, and file input/output. Includes specialized tools for astronomers.

Sunwait calculates sunrise or sunset times with civil, nautical, astronomical and custom twilights. The sun's position is calculated using time, and position - latitude and longitude should be specified on the command line.

Features:

• calculates sunrise and sunset for given coordinates

• can wait for sunrise/sunset, or return DAY or NIGHT codes

• works with Windows Task Scheduler (or cron)

• supports custom twilight angles

• used to automate domestic lighting with Arduino transmitter and radio controlled sockets

Astral is a Python module that calculates times for various positions of the sun: dawn, sunrise, solar noon, sunset, dusk, solar elevation, solar azimuth, rahukaalam, and the phases of the moon.

This package provides an Updated and improved version of the Sparse Lens Inversion Technique, developed within the framework of lens modelling software lenstronomy.

This package provides a python library to calculate IACT IRF and Sensitivities.

This package implements functionality for simulating X-ray emission from astrophysical sources.

X-rays probe the high-energy universe, from hot galaxy clusters to compact objects such as neutron stars and black holes and many interesting sources in between. pyXSIM makes it possible to generate synthetic X-ray observations of these sources from a wide variety of models, whether from grid-based simulation codes such as FLASH, Enzo, and Athena, to particle-based codes such as Gadget and AREPO, and even from datasets that have been created 'by hand', such as from NumPy arrays. pyXSIM also provides facilities for manipulating the synthetic observations it produces in various ways, as well as ways to export the simulated X-ray events to other software packages to simulate the end products of specific X-ray observatories.

Generalized World Coordinate System (GWCS) is an Astropy affiliated package providing tools for managing the World Coordinate System of astronomical data.

GWCS takes a general approach to the problem of expressing transformations between pixel and world coordinates. It supports a data model which includes the entire transformation pipeline from input coordinates (detector by default) to world coordinates.

LibXISF is C++ library that can read and write XISF files produced by PixInsight. It implements XISF 1.0 specification.

stsci.imagestats is a package designed to compute various statistics on image data using sigma-clipping iterations. It is designed to replicate core behaviour of the IRAF's imstatistics task.

SunPy is package for solar physics and is meant to be a free alternative to the SolarSoft data analysis environment.

It includes an interface for searching and downloading data from multiple data providers, data containers for image and time series data, commonly used solar coordinate frames and associated transformations, as well as other functionality needed for solar data analysis.

SkyMaker is a program that simulates astronomical images. It accepts object lists in ASCII generated by the Stuff program to produce realistic astronomical fields. SkyMaker is part of the EFIGI development project.

European Southern Observatory Data Processing System EDPS is a system to automatically organise data from ESO instruments for pipeline processing and running the pipeline on these data. It is used for quality control at ESO. The current public release is a beta version without a GUI. A GUI is being developed and the system is meant to eventually replace the older EsoReflex environment.

This package provides a a simple program to predict the levels of background emission in JWST observations, for use in proposal planning.

It accesses a precompiled background cache prepared by Space Telescope Science Institute. The background cache is hosted by the Mikulski Archive for Space Telescopes (MAST), so you need internet access to run the tool with the remote cache. It is possible to download the full background cache to your local machine.

This package provides information about the Euclid space telescope and survey that is needed to produce simulations using GalSim. Some of the information provided is approximate, aimed towards fast simulations rather than full accuracy in representation of Euclid images. Places where the information is only approximate are flagged and described in the docstring, and we particularly highlight that the PSF is only approximate; for details, see the docstring of the getPSF() method. This library should enable generation of Euclid-like images of sufficient fidelity for preliminary exploration of object detection, photometry, deblending, and joint analysis with ground-based observatories. For applications requiring high precision such as weak lensing, the higher fidelity simulations available within the Euclid Consortium should be used.

This package provides a flexible toolbox for observation planning and scheduling. When complete, the goal is to be easy for Python beginners and new observers to to pick up, but powerful enough for observatories preparing nightly and long-term schedules.

Features:

• calculate rise/set/meridian transit times, alt/az positions for targets at observatories anywhere on Earth

• built-in plotting convenience functions for standard observation planning plots (airmass, parallactic angle, sky maps)

• determining observability of sets of targets given an arbitrary set of constraints (i.e., altitude, airmass, moon separation/illumination, etc.)

This package provides a collection of Space Telescope Science Institute utility functions.
