Telescope

class prose.Telescope

Object containing telescope information.

Once a new telescope is instantiated its dictionary is permanantly saved by prose and automatically used whenever the telescope name is encountered in a fits header. Saved telescopesare located in ~/.prose as .telescope files (yaml format).

Example

from prose import Telescope

telescope_dict = dict(
    # Name(s)
    # -------
    name = "Unknown",
    names = [],

    # Keywords
    # --------

    keyword_image_type = "IMAGETYP",

    keyword_dark_images = "dark",
    keyword_flat_images = "flat",
    keyword_bias_images = "bias",
    keyword_observation_date = "DATE-OBS",
    keyword_exposure_time = "EXPTIME",

    keyword_airmass = "AIRMASS",

    keyword_dec = "DEC",
