get_epic_images(filename, band=[], instrument=[], get_detmask=False, get_exposure_map=False, path='', **kwargs)[source]

Extracts the EPIC images from a given TAR file

This function extracts the EPIC images in a given band (or bands) and instrument (or instruments) from it

The result is a dictionary containing the paths to the extracted EPIC images with keys being the band and the instrument

If the band or the instrument are not specified this function will return all the available bands and instruments

Additionally, get_detmask and get_exposure_map can be set to True. If so, this function will also extract the exposure maps and detector masks within the specified bands and instruments

Parameters:
filenamestring, mandatory

The name of the tarfile to be proccessed

bandarray of integers, optional, default []

An array of intergers indicating the desired bands

instrumentsarray of strings, optional, default []

An array of strings indicating the desired instruments

get_detmaskbool, optional

If True, also extracts the detector masks

get_exposure_mapbool, optional

If True, also extracts the exposure maps

path: string, optional

If set, extracts the EPIC images in the indicated path

Returns:
A dictionary of dictionaries with the full paths of the extracted
EPIC images. The keys of each dictionary are the band for the first
level dictionary and the instrument for the second level dictionaries

Notes

The structure and the content of the extracted compressed FITS files are described in details in the Pipeline Products Description [XMM-SOC-GEN-ICD-0024](https://xmm-tools.cosmos.esa.int/external/xmm_obs_info/odf/data/docs/XMM-SOC-GEN-ICD-0024.pdf).

get_epic_lightcurve(filename, source_number, *, instrument=[], path='')[source]

Extracts the EPIC sources light curve products from a given TAR file

For a given TAR file obtained with XMMNewton.download_data.

This function extracts the EPIC sources light curve products in a given instrument (or instruments) from said TAR file

The result is a dictionary containing the paths to the extracted EPIC sources light curve products with the key being the instrument

If the instrument is not specified, this function will return all available instruments

Parameters:
filenamestring, mandatory

The name of the tarfile to be proccessed

source_numberinteger, mandatory

The source number, in decimal, in the observation

instrumentsarray of strings, optional, default []

An array of strings indicating the desired instruments

path: string, optional

If set, extracts the EPIC images in the indicated path

Returns:
A dictionary with the full paths of the extracted EPIC sources
light curve products. The key is the instrument

Notes

The filenames will contain the source number in hexadecimal, as this is the convention used by the pipeline.
