vdrp.programs.call_fit2d(ra, dec, outname, wdir)

Call fit2d. Calculate the 2D spatial fit based on fwhm, fiber locations, and ADC. This convolves the PSF over each fiber, for a given input position. It fits the ampltiude, minimizing to a chi^2.

Requires input files generated by run_fit2d

Parameters:

ra : float

Right Ascension of the star.

dec : float

Declination of the star.

outname : str

Output filename.

wdir : str

Name of the work directory

vdrp.programs.call_fitem(wl, wdir)

Call fitem requires input files created by run_fitem

The line fitter. It fits a gauss-hermite. input is fitghsp.in.

Parameters:

wl : float

Wavelength

vdrp.programs.call_fitonevp(wave, outname, wdir)

Call fitonevp

Requires fitghsp.in created by apply_factor_spline

Parameters:

wave : float

Wavelength

outname : str

Output filename

wdir : str

Name of the work directory

vdrp.programs.call_getnormexp(nightshot, wdir)

Call getnormexp. Get fwhm and relative normalizations for the frames.

Parameters:

name : str

Observation name

vdrp.programs.call_imextsp(filename, ifuslot, wl, wlw, tpavg, norm, outfile, wdir)

Equivalent of the rextsp script, a wrapper around the imextsp fortran routine.

Extracts the spectrum from the multi fits files and writes the tmp*dat. This also calculates the appropriate photon errors, using counting and sky residual errors. This applies the throughput and fiber to fiber.

Parameters:

filename : str

The filename to process

ifuslot : str

The ifuslot name

wl : float

The central extraction wavelength

wlw : float

The width of the extraction window around wl

tpavg : float

Throughput average for the spectrum

norm : str

File with fiber to fiber normaliztion for the spectrum

outfile : str

Name of the output filename

wdir : str

Name of the work directory

vdrp.programs.call_mkimage(ra, dec, starobs, wdir)

Call mkimage, equivalent of rmkim

Reads the out2d file and creates three images of the emission line data, best fit model and residuals, called im[123].fits.

Parameters:

ra : float

Right Ascension of the star.

dec : float

Declination of the star.

starobs : list

List of StarObservation objects for the star

vdrp.programs.call_mkimage3d(wdir)

Run the mkimage3d command, creating an output file called image3d.fits

vdrp.programs.call_sumspec(starname, wdir)

Call sumpspec. Sums a set of spectra, and then bins to 100AA bins. Used for SED fitting.

Parameters:

starname : str

Star name used to create the outputn filename (adds specf.dat)

vdrp.programs.call_sumsplines(nspec, wdir)

Call sumsplines, calculate a straight sum of the spectra in a list, including errors. Expects the spectra to be called tmp101 to tmp100+nspec.

Creates a file called splines.out

Parameters:

nspec : int

Number of spectra to read.

wdir : str

Name of the work directory

vdrp.programs.run_fitradecsp(ra, dec, step, nstep, w_center, w_range, ifit1, starobs, specfiles, wdir)

Setup and call fitradecsp. This creates a file called spec.out

Parameters:

starobs : list

List of StarObservation structures one for each fiber

specfiles : list

List of filename of the different spec files
