STDWeb Documentation
====================

**STDWeb** (Simple Transient Detection for the Web) is a web-based tool for quick-look photometry and transient detection in astronomical images. It is based on the `STDPipe <https://github.com/karpov-sv/stdpipe>`_ library and implements a self-consistent, mostly automatic data analysis workflow.

Features
--------

- Upload your own FITS files or analyze files already on the server
- Basic pre-processing and masking
- Object detection with astrometric calibration (blind matching or WCS refinement)
- Photometric calibration using multiple reference catalogs
- Template subtraction with automatically downloaded or user-provided templates
- Forced photometry for specified targets in original or difference images
- Transient detection in difference images

For details on the underlying routines, see the `STDPipe documentation <https://stdpipe.readthedocs.io/>`_ and `example notebooks <https://github.com/karpov-sv/stdpipe/tree/master/notebooks>`_.
