Release note for v0_02 (10 Dec 2024)
 This is an internal data release for Hector, version v0.02.
 If your have any queries, please contact Sree Oh (sreemario@gmail.com) and Madusha Gunawardhana (madusha.gunawardhana@sydney.edu.au).

1. Release catalogue: release_catalogue_v0_02.csv
  name = galaxy id
  filename = cube filename
  ccd = blue(BL) or red(RD) arm
  identifier = cube identifier (A-Z)
  version = version of data release
  infile = original cube name
  runid = observing run id
  ra, dec = right ascension, declination
  xcen, ycen = x, y centres of the cube (target)
  texp = integrated exposure time
  ndither = number of RSS frames combined for the cube
  inst = instrument name 
  probe = Hexabundle name
  tile = tile name
  field = filed name (all values are 1 for Hector but SAMI will have values)
  type = object type. star(S) or galaxy(G)
  fwhm = mean PSF FWHM in arcsec
  trans = mean relative transmission

  note. 
  - We removed the 'source' column from v0_02. Instead, the source of the object (WAVES (W), Cluster (W), and Star (S)) is now represented as a prefix in the 'name' column.
  - The identifier "A" does not specifically indicate the best cube when there are repeats. Users are expected to select their cubes based on FWHM and transmission.

  Please note that we exclude 220817_220904 and 220914_220925 from v0_02, finding incorrect information from the input catalogue. 
  Also, 221019_221030 is considered commissioning runs. Exercise caution when using commissioning data.

3. v0_02 Cubes (~ 411G)
  Data releases v0_02 release 5304 cubes including 1664 (corrected this number on 12 Dec 2024; it miscounted as 2102 in the original release note) unique galaxies
  The cubes are uploaded to the data central clouds:
  https://cloud.datacentral.org.au/apps/files/?dir=/Hector/Data_Release/release_v0_02
  All the cubes are compressed

  It is recommanded to use rsync:
  rsync -avhPi -e 'ssh -p 2232' hector@uploads.datacentral.org.au:/data/Data_Release/release_v0_02 ./

4. New features in v0_02
  - More accurate and stable arc solutions using 2D arc modeling
  - Improved flux calibrations
    - Removed inaccurate primary standard stars and applied median Transfer function where necessary
    - Adjusted spline fit for a better fit to the transfer function 
    - Improved standard star extraction and Moffat fitting
    - Improved CvD corrections
    - Disabled incorrect arc solutions caused by using the wrong arc lamp
    - Applied proper quality control based on FWHM and transmission values
  - Cubes
    - Corrected cube orientations
    - Adopted a drop size of 0.75
    - Removed holes in cubes by not applying throughput clipping
    - All cubes now have a prefix (S, W, C) in their file names

 Then, enjoy the cubes!
