This file contains update or claification to the 1610-IRTF_ops_concept_5 document.

1.  manifest file.

Rename/move the  $DATE_manifest to be $DATE/manifest (putting inside the $DATE directory) 

The $DATE/manifest.sha256 file is used to indicated the $DATE/manifest file is complete
and data transfer for $DATE is ready. Commands to produce manifest files are:
Note: added "-k 2 " to sort command to sort on column 2 (filenames)

   cd $DATE/
   find . -type f -print0 | xargs --null -n 1 sha256sum | sort -k 2 > manifest

   sha256sum manifest > manifest.sha256

The manifest.sha256 file should be the last file transfer during upload to IPAC.

2.  ishell darks  

This text can be removed:

   ISHELL only:
   IRTF/$SEMESTER/$DATE/data/darks/*.fits
   or a specific PROGRAM_ID reserved for ISHELL darks instead of “darks/”

iSHELL darks files files will appear in at $PROGRAM_ID/$GROUP_ID/*.fits
using the same structure as the other FITS files.

3. Deliveries    

Per our discussion on Feb 5/6:

  Initial deliveries would consist entirely of files under the IRTF/$SEM/$DATE directory.

  Any updated to the summary files would replace the entire IRTF/$SEM/$DATE/summary/ tree, and consist of:
     /IRTF/$SEM/$DATE/manifest
     /IRTF/$SEM/$DATE/manifest.sha256
     /IRTF/$SEM/$DATE/summary/*
