Updates to Keywords on December 14, 2021

On December 14, 2021, KOA is updating the following HIRES keywords in our tables:

IMAGETYP will be replaced with KOAIMTYP
PROPMIN, PROPINT1, PROPINT2, PROPINT3 will be replaced by PROPINT

In addition, for users who rely on any of the following products, please note that they will use KOAIMTYP and PROPINT for all instruments, instead of deprecated keyword names IMAGETYP and PROPMIN:

IPAC ASCII tables, available at the bottom of the search results page
All *.caliblist files, included when users search for science files with associated calibrations
Results from PyKOA queries (we have updated the sample notebooks to use the new keyword names)
HIRES TAP queries

New HIRES data obtained on or after December 14, 2021 will have the keyword KOAIMTYP instead of IMAGETYP in their FITS headers. PROPINT is not present in the FITS headers and is only used in our tables.
