Software
From Tauwiki
Programs written by the TAUVEX group
A list of available software, developed by the TAUVEX group is listed here. Tools here fall into two classes, a) those designed for TAUVEX mission, to help define the observations and to understand which classes of objects may or may not be observed, and b) general science tools.

[edit] TAUVEX Tools
[edit] Exposure Time Calculator
The Exposure Time Calculator (ETC) is intended to allow the user to calculate the exposure time needed for different classes of objects for a given S/N or, alternatively, to calculate the S/N for a given exposure time.

[edit] Observation Planning Tool
Observation Planning Tool calculates the observable dates for a given sky coordinate. This tool calculates sun and moon angles to identify observable period. Zodiacal light contribution is also calculated.

[edit] Sky Simulation Tool
The primary aim for our Sky Simulation Software is to generate test data for data pipeline system and for science mission planning. While the software itself is generic, the online interface is more focused on TAUVEX, with additional modules to estimate straylight and zodiacal light contribution for TAUVEX filters and the detector nonlinearity effects for TAUVEX. Written in C (ANSI), the source code and binaries for a few platforms are available in the Download Area.

[edit] ascii2fits
This program converts the event list (ascii) output of Sky Simulation tool into fits images. ascii2fits is written in C (ANSI). The source code is available in the Download Area.
[edit] Detector Nonlinearity
This software applies the non-linear response curve of TAUVEX detectors (at high event rates) to the event list generated by the sky simulation software.
[edit] Science Tools
As part of our program development and science activities, we have written a set of science tools for such actions as calculating Kurucz models for given spectral types and for calculating the interstellar radiation field (ISRF) at different locations in the sky (needed for our diffuse radiation models), Astronomical Coordinate Conversions etc.
[edit] Coordinate Converter
Coordinate Converter is a java applet which can be either used online or downloaded.

[edit] Zodiacal Light Calculator
This tool calculates the zodiacal light spectrum from a given location in the sky at a given date. The web interface is primarily for TAUVEX mission planning. Backend is written in C (ANSI). The source code is available in the Download Area.

[edit] Stellar Flux Calculator
Stellar Flux Calculator generates the star spectrum for a given magnitude, spectral type and E(B-V). Based on Kurucz models. Backend is written in C (ANSI). The source code is available in the Download Area. This software is used by TAUVEX ETC and a number of other tools to generate stellar spectra.

[edit] ISRF Calculator
Interstellar Radiation Field Calculator, aka ISRF Calculator, is based on Stellar Flux Calculator. For any given location in sky, it calculates the total radiation fields from the contribution of stars in the vicinity. Star catalog used here is Hipparcos.

[edit] fits to jpeg Converter
This software converts fits images to jpeg. Provision exists to apply an intensity/flux scaling option for improving the visibility of features within the limiter dynamic range of bitmap formats. Scaling options are: linear/log/square-root/square/cube. Users can apply histogram equalization or linear contrast stretch as well. This software is written in C (ANSI). Source code is available in the Download Area.
[edit] UV Background Simulation
UV Background Simulator uses available GALEX data, hipparcos catalog (via Stellar Flux Calculator) and Zodiacal light calculator to simulate an image of the sky. User may choose a filter from our list or upload new, define telescope parameters, specify a day (for zodiacal light), define the coordinate frame and image parameters (resolution, projection etc).

[edit] Table to Fits Image Converter
This software does most of the backend work for UV Background simulator. It reads a list of locations and fluxes from as ascii file and generates a fits image from the data. It interpolates across regions where data is not available. Coordinate conversions (galactic/equatorial/ecliptic) can be performed on input data. Image parameters are also configurable. Source code is written in C (ANSI) and is available in the Download Area.
