*
* Source of method:
* Fifth Fundamental Catalogue (FK5) Part I (1988, but not avail. till 1992)
* Section 8. (page 9)
* Summary of order:
* 1. Precess each object (using precessional values adopted in that cat-
* i.e. usually Newcomb) from the catalogue equinox to the mean equinox
* at the object's mean epoch (i.e. observation date).
* 2. The mean positions in all star catalogues published prior to 1984
* contain the terms of elliptic aberration (E-terms). These terms need
* to be removed from the star's mean position.
* 3. The equinox correction and the systematic correction FK5-FK4
* (given in the FK5 cat), computed for the object's mean epoch, need to
* be applied. Note: program applies fk5-fk4 sys.corr. at B1950 which
* seems consistent with procedure actually described in the FK5.
* 4. The corrected position has to be precessed to the new standard equinox
* J2000.0 using the precessional quantities as adopted in the IAU(1976)
* System of Astronomical Constants (also see Astronomical Almanac 1984,
* pages S34,S36)
*
* NOTE: these routines apply the fk5-fk4 correction at B1950.
* if no fk5-fk4 systematic correction required, the user should
* include the following statements in his program:
* (a value of 0 for japply specifies no corrections; anything else uses corr.)
* external jfk5bd
* common /fkappl/ japply
* japply = 0
*
* ****************************************************************************
* All arguments are double precision, except ieflg which is integer.
* Input values:
* eqxin is the equinox of the input position (if negative, absolute val.used)
* ra is right ascension (decimal degrees) at eqx
* dec is declination (decimal degrees) at eqx
* tobsin is the year of observation (i.e. when the object was observed at
* this position (e.g. 1983.5d0) ; if 0.0d0, value of eqxin is used.
* ieflg is flag allowing removal of E-terms of aberration if any (usually
* they are present, therefore ieflg should = +1):
* ieflg = -1 do not remove E-terms (there none).
* ieflg = any value except -1 indicates E-terms are present and

Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
Polynomials over GF(2) are represented in binary, one bit per coefficient,
with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
x (which is shifting right by one and adding x^32 mod p if the bit shifted
out is a one). We start with the highest power (least significant bit) of
q and repeat for all eight bits of q.
The table is simply the CRC of all possible eight bit values. This is all
the information needed to generate CRC's on data a byte at a time for all
combinations of CRC register values and incoming bytes.
