(

filepath

)

Read a WSO/WSO V0 ascii format file from wso.stanford.edu/synoptic database.

Returns

module_map2D.Map2D() object.

WSO V0 ascii format is the following:
Header: some lines
CTXXXX:longitude[0] 6f7.3 /n 8f7.3 /n 8f7.3 /n 8f7.3
...
CTXXXX: longitude[i] 6f7.3 /n 8f7.3 /n 8f7.3 /n 8f7.3
...
CTYYYY:longitude[0] 6f7.3 /n 8f7.3 /n 8f7.3 /n 8f7.3

Where XXXX is a Carrington rotation and YYYY is the following one

def readmap2D.module_wso_wso_map2D.read_v1

(

filename

)

Read a WSO-V1-Ascii file an return a Map2D object.

Format V1 for WSO is like this:

• No header.
• Data: (nlon x nlat) = (72 x 30). Written on 8 columns with fortran indexing (by column). 8(F10.4) format.
• Longitude goes from 2.5 to 357.5 with 5 degree step.
• Latitude goes from ]asin(-14.5/15)..asin(+14.5/15)[.

Translated into python from CORFIELD/dir.src/corfield_read_data.f90.

Todo:

Create format WSO-V2-Ascii with 8(F10.4,1x).

def readmap2D.module_wso_wso_map2D.write_v1	(		data_map2D,
			filename
	)

Write a Map2D object in an ascii file following format V1:

• No header.
• Data: (nlon x nlat) = (72 x 30). Written on 8 columns with fortran indexing (by column). 8(F10.4) format.
