Slicer

class mpdaf.MUSE.Slicer[source]

Bases: object

Convert slice number between the various numbering schemes.

The definition of the various numbering schemes and the conversion table can be found in the “Global Positioning System” document (VLT-TRE-MUSE-14670-0657).

All the methods are static and thus there is no need to instanciate an object to use this class.

Examples

Convert slice number 4 in CCD numbering to SKY numbering :

>>> print(Slicer.ccd2sky(4))
10
>>> print(Slicer.sky2ccd(10))
4

Convert slice number 12 of stack 3 in OPTICAL numbering to SKY numbering:

>>> print(Slicer.optical2sky((2, 12)))
25
>>> print(Slicer.sky2optical(25))
(2, 12)

Convert slice number 12 of stack 3 in OPTICAL numbering to CCD numbering:

>>> print(Slicer.optical2ccd((2, 12)))
27
>>> print(Slicer.ccd2optical(27))
(2, 12)
