This revision * Admits "yzLN"/"yzLT" CTYPE codes for longitude/latitude axis pairs; it was felt that the 26 possibilities for "xLON"/"xLAT" would not be enough. * Augments the distortion function for the TAN projection to include 7th order terms. This is sufficient to account for the complex distortions found in Schmidt plates. * Includes another header construction example, this one describing selenographic coordinates for an image of the moon. Time is running out to make further comments!

Two in this message. On the subject of primary and secondary axis descriptions, the paper does not say explicitly that one cannot have secondary descriptions without a primary (i.e., say, CTYPE1P without there being a CTYPE1). I don't think that is intended and it may be a good idea to say explicitly that one can have a primary axis description without any secondaries, but no secondary without a primary. On the same subject, it may be good to clarify explicitly whether it is allowed to have duplications (say, one has CTYPE1, CTYPE1A, CTYPE1B, CTYPE1C, CTYPE1P, CTYPE1Q; and it so happens that CTYPE1=CTYPE1C=CTYPE1C). I must admit that I shudder at the thought, but others may want to attach special meanings to particular secondary identifiers (P for physical, for instance) which could force one into these duplications. The second is RADECSYS. I think we need more values. Chandra is going to churn out FITS files with RADECSYS='ICRS'; FK5 is certainly not appropriate anymore. - Arnold -------------------------------------------------------------------------- Arnold H.
