Pythonic tool to work with Aladin Lite

Check these links:

• Build an interactive sky map with Aladin Lite
  
• Image surveys
  
• REST api example
  

Example 1 : add surveys and markers

from aladin import Aladin

a = Aladin(target='270.6003707 -23.0224839')

buttons = [
    ('P/2MASS/color', 'bs 2MASS'),
    ('P/GLIMPSE360', 'bs GLIMPSE 360'),
    ]

markers = [
    (270.332621, -23.078944, 'PSR B1758-23', 'Object type: Pulsar'),
    (270.63206,  -22.905550, 'HD 164514',    'Object type: Star in cluster'),
    (270.598121, -23.030819, 'HD 164492',    'Object type: Double star'),
    ]

a.add_survey_buttons(buttons)
a.add_markers(markers)

a.create()
a.save('index.html')

Example 2 : add SIMBAD and VizieR layers

from aladin import Aladin

a = Aladin(target='270.6003707 -23.0224839')

a.add_simbad()

a.add_vizier('I/239/hip_main')

a.create()
a.save('index.html')

You can pass optional arguments target and radius to both add_simbad and add_vizier methods.

Example 3 : Southern-Ring-Nebula from JWST as overlay layer

from aladin import Aladin

a = Aladin(target='151.75735684271, -40.43642515362001', fov=0.1)

buttons = [
    ('P/2MASS/color', '2MASS'),
    ('P/DSS2/color', 'DSS'),
    ]

a.add_survey_buttons(buttons)

hips_id = 'CDS/P/JWST/Southern-Ring-Nebula/NIRCam'
hips_name = 'Southern-Ring-Nebula'
hips_base_url = 'https://alasky.cds.unistra.fr/JWST/CDS_P_JWST_Southern-Ring-Nebula_NIRCam'
hips_max_ord = 14

a.add_image_overlayer(hips_id, hips_name, hips_base_url, hips_max_ord, slider=True)

a.create()
a.save('index.html')
