TraceSet¶
- class pydl.pydlutils.trace.TraceSet(*args, **kwargs)[source]¶
Bases:
object
Implements the idea of a trace set.
- Attributes:
- func
str
Name of function type used to fit the trace set.
- xminfloat-like
Minimum x value.
- xmaxfloat-like
Maximum x value.
- coeffarray-like
Coefficients of the trace set fit.
- nTrace
int
Number of traces in the object.
- ncoeff
int
Number of coefficients of the trace set fit.
- xjumplofloat-like
Jump value, for BOSS readouts.
- xjumphifloat-like
Jump value, for BOSS readouts.
- xjumpvalfloat-like
Jump value, for BOSS readouts.
- outmaskarray-like
When initialized with x,y positions, this contains the rejected points.
- yfitarray-like
When initialized with x,y positions, this contains the fitted y values.
- func
This class can be initialized either with a set of xy positions, or with a trace set HDU from a FITS file.
Attributes Summary
True
if jump conditions are set.Number of x values.
Range of x values.
Midpoint of x values.
Methods Summary
xnorm
(xinput, jump)Convert input x coordinates to normalized coordinates suitable for input to special polynomials.
xy
([xpos, ignore_jump])Convert from a trace set to an array of x,y positions.
