input_coo

source

.input_coo(
   input_par, source
)

---

Take input parameters and parse them as an astropy table for comparison with DAOphot.

Args

• input_par : input parameters, e.g., from input_parameters.py.
• source (Source object) : the Source object containing all of the sources simulated.

Returns

trimmed_cat = an astropy table containing the TRUE input positions (static distortion, sub-pixel positioning and proper motion taken into account) and additional information necessary to compare with the DAOPhot output.

add_all_noise

source

.add_all_noise(
   input_par, image, exp_time
)

---

Adds all noise effects onto noiseless image.

Args

• input_par : input parameters object.
• image (np.ndarray) : 2D noise-free image.
• exp_time (float) : total exposure time in seconds.

Returns

• image_adu (np.ndarray) : final image + noise in ADU

make_static_dist_map

source

.make_static_dist_map(
   input_par
)

---

Make static distortion map from loaded distortion samples in input_par.

Args

• input_par : input parameters object.

Returns

dist_x_func_degmm: dist_y_func_degmm:
