1) Different processors are in use for the production of IRS-P6 and IRS-1C/1D data products at GAF. Even so the document describes also a format for IRS-1C/1D, only the document under the column 'IRS-1C/1D' is applicable for IRS-1C/1D products processed by GAF.
2) The IRS-P6 document describes the GeoTIFF for IRS-P6 data products as generated by the DPGS processor and offered by some ground stations. However, the band separated GeoTIFFs delivered as part of the GAF Ortho Kit for IRS-P6 are not generated by the DPGS, are very basic, and a describing document does not exist.

IRS data products are provided via the Internet using the FTP protocol.
