Gris WCS: CTYPE should be HP instead of HG

Excempt from rocketchat:

Vigeesh: Question about GRIS data header

WCSNAME = 'Helioprojective Cartesian' / nan
CTYPE1  = 'HGLN-TAN'           / Type of coordinates along axis 1
CUNIT1  = 'arcsec  '           / Units along axis 1
CRPIX1  =                    0 / Reference pixel
CRVAL1  =             -393.014 / Value at reference pixel on axis 1
CDELT1  =             0.027174 / Sampling along axis 1

HGLN-TAN according to Thompson et al refers to Stonyhurst heliographic longitude so, I'm a bit confused about why it is called "Helioprojective Cartesian"? also the CDELT1 is in HGLN-TAN or HPLN-TAN?

schaffer 10:56 AM You're right, that is inconsistent. I believe CTYPE should be HPLT-TAN, at least that is what is being done under the hood. I'll open an issue and correct this in all files sometime in the near future.

• fix code
• re-format files
• re-upload files to archive
