srclists

class srclists.Component_Info

Class to contain an RTS source information

Variables:

• comp_type (str) – The component type: either POINT, GAUSSIAN, or SHAPELET
• pa (float) – Position Angle of the component
• major (float) – Major angle of the component
• minor (float) – Minor angle of the component
• shapelet_coeffs (list) – List to contain lists of shapelet coeffs if the source is a SHAPELET

class srclists.RTS_source

Class to contain an RTS source information

Variables:

• name (str) – Source name
• ras (list) – List of all RA for all components in this source
• decs (list) – List of all Dec for all components in this source
• flux_lines (list) – List to contain list of flux lines for all components in this source
• component_infos (list) – List to contain Component_Info classes for all components in this source

srclists.check_rts_or_woden_get_lines(filename)

Opens the file at path filename, and splits into lines by return carriage. Ignores all lines commented with #. Uses the first line of the file to determine if this is an RTS or WODEN style srclist

Parameters:filename (string) – Path to a text file Returns:

• type (string) – The type of srclist, either “woden” or “rts”
• lines (list) – The lines of the file as string, split by return carriage, in a list

srclists.get_RTS_sources(srclist, all_RTS_sources)

Takes a path to an RTS srclist, breaks it up into SOURCES, populates this information into RTS_source classes and appends them to all_RTS_sources list

Parameters:

• srclist (string) – Path to a texfile of an RTS srclist
• all_RTS_sources (list) – All sources found in srclist are used to populate an RTS_source class, and appended to all_RTS_sources

Returns:

all_RTS_sources – The original all_RTS_sources list, with any new RTS_source s appended

Return type:

list of RTS_source

srclists.write_singleRTS_from_RTS_sources(RTS_sources, outname, name='combined_name')

Takes a list RTS_sources containg RTS_source classes, and writes them out into a single SOURCE RTS srclist of name outname

srclists.write_woden_component_as_RTS(lines, outfile, name=False)

Take in a number of text lines in the WODEN format and writes them out to outfile in the RTS format

Parameters:

• lines (list) – A list of strings, each a line from a WODEN style srclist
• outfile (open(filename) instance) – An opened textfile to write outputs to
• name (string) – If a name is supplied, this is the first component of a SOURCE, which requires extra formatting in an RTS srclist

srclists.write_woden_from_RTS_sources(RTS_sources, outname)

Takes a list of RTS_source classes and uses the to write a WODEN style srclist called outname

Parameters:

• RTS_sources (list) – A list of RTS_source s to write out to a WODEN style srclist
• outname (string) – Path to save the output WODEN srclist text file to
