add_magzp_headers()

Add magnitude zero-point values to the image headers.

calibrate_stamps()

Calibrate the downloaded stamps.

check_zero_points()

Check if zero-point magnitudes are available.

property conn

Get the connection object to the S-PLUS Cloud.

Returns:

Connection object to the S-PLUS Cloud.

Return type:

object

create_cube(flam_scale=None)

Create a data cube from S-PLUS galaxy stamps.

Parameters:

flam_scale (float, optional) – Scaling factor for flux density, by default None.

Raises:

OSError – Raises an error if the cube already exists and redo is not specified.

create_metadata_hdu(keys=None)

Create a metadata table HDU.

Parameters:

keys (list, optional) – List of header keys, by default None.

Download the Lupton RGB image.

get_stamps()

Download stamps for each band.

get_zero_points()

Get zero points from the specified table.

get_zero_points_correction()

Get corrections for zero points.

XXX: 2025-03-14 - EADL@RV

zp correction image is based on a 9200 x 9200 image, the valid CCD area. When creating stamps, the stamp FITS header maps the x0, y0 position on the original 11000 x 11000 field image. This creates a huge problem on correcting stamps.

remove_downloaded_data()

Remove downloaded stamp, detection image, and Lupton RGB image files.

spectra(flam_scale=None)

Parameters:

flam_scale (float, optional) – Scaling factor for flux density, by default None.

Parameters:

header (Header) – FITS header containing WCS information.

Returns:

Cube header with updated WCS information.

Return type:

Header
