Trait for 1D Extracted spectra from NEID

Trait for 2D Extracted spectra from NEID

Trait to specify any 1D or 2D Extracted spectra from NEID

make_clean_line_list_from_tellurics(line_list, neid_data; Δv_to_avoid_tellurics ) Returns a new line list that excludes lines with telluric contamination. Inputs:

• line_list: Dataframe containing field lambda

- neid_data: Array of spectra

• Δv_to_avoid_tellurics: in m/s
• v_center_to_avoid_tellurics : in m/s
• tellurics_filename: filename with wavelength ranges affected by tellurics

Outputs:

• line_list_without_tellurics: DataFrame with fields: lambda, weight, lambda_lo, and lambda_hi.

Warning: Currently, reads in a list of wavelength ranges with tellurics and this file was created based on tellurics metadata in EXPRES data for HR 101501.

Create Dataframe containing filenames and key data for all files neid*.fits in directory

Create Dict containing filename and default metadata from file.

Read blaze for NEID science fiber from FITS file.

Read calibrator data

Read NEID data from FITS file, and return in a Spectra2DBasic object.

Read space delimited file with differential extinction corrections, interpolate to bjd's in df and insert into df[:,diffextrv].

Create Dict containing filename and default metadata from file.

Create Dict containing filename and default metadata from file.

Read normalization function for approximate solar continuum+blaze correction TODO: Figure out mapping between these orders and what's stored in the FITS file before using.

readtelluricranges( filename ) Return DataFrame (keys lambdalo and lambdahi) with wavelength ranges to be avoided as containing tellurics based on provided CSV file. Assumes path is included in filename.
